No, there is no need to recompile the whole kernel. Just the graphics driver, which is a kernel module.
To come back to the issue. I can run the graphics with the kernel 3,2,3-2 and if it does not work with the new kernel 3,2,5-3, I can only think that the new kernel has not been build up properly. However, when I compare the 2 files /usr/src/kernels/3.2.3-2.fc16.x86_64/.config and /usr/src/kernels/3.2.5-3.fc16.x86_64/.config they are identical. Then I can deduce that is is probably a modules issues.
Precisely. The kernel configs have nothing to do with the graphics driver. The graphics driver is a kernel module, and apparently you have one for the 3.2.3-2 kernel, while you don't have it for the 3.2.5-3 kernel.
lsmod does seem to show that the module nvidia.ko is loaded
No, it doesn't, the word "nvidia" doesn't appear anywhere in the list. See below for an explanation.

Ok, this is how it all works. The driver for your nVidia graphics hardware is a kernel module. The module version has to match the kernel version, so you need one driver module for each kernel. Technically speaking, the module needs to be built "against the appropriate kernel", typically while that kernel is running.
There are two different graphics drivers for nVidia cards. One is called "nouveau", and is an open-source driver provided by Fedora out-of-the-box. The other is called "nvidia", and is a closed-source driver provided by nVidia (also commonly called "binary blob"). The nvidia driver mostly works better than nouveau, since nouveau is still under development.
Nouveau and nvidia modules cannot coexist. If nouveau is to work properly, nvidia driver must be uninstalled from the machine. If nvidia is to work properly, nouveau needs to be blacklisted and unistalled from the initrd. Since the Fedora's kernel automatically loads nouveau on boot (if it is not blacklisted), one needs to reboot the machine in order to switch from nouveau to nvidia (or vice-versa).
The nvidia driver can be obtained in two different ways. One way is to download the appropriate .run file from nVidia website and run it. This is the *wrong* way, since it doesn't play nice with Fedora, overwrites some system files, and is a pain to remove once installed. The other way is to install (via yum) the package called akmod-nvidia, which is provided by the rpmfusion repository. This is the *correct* way, since that package was designed precisely for Fedora, doesn't overwrite system files and can be easily removed. The driver itself (the nvidia kernel module) is the same as the one provided by nVidia website --- the difference is in the details of the installation procedure.
For your situation, I suggest the following:(1) Run "yum update". There is a new kernel available (3.2.6-3), and you should install it.
(2) Run "mv /etc/X11/xorg.conf /etc/X11/xorg.conf-backup". This will rename the xorg.conf file (if you have it), and let X run with default configuration (i.e. without an xorg.conf file) after a reboot.
======================================================================= This is probably were my problem is. I removed the /etc/X11/xorg.conf because if it is here I can never start my graphic mode with the rigth resolution. So I use /etc/X11/xorg.conf.d with the following files:00-nvidia.conf 00-system-setup-keyboard.conf 40-monitor.conf 50-screen.conf (see attached file)
How is is connectred to nouveau and nvdia? For now I have: xorg-x11-drv-nouveau-0.0.16-27.20110720gitb806e3f.fc16.x86_64 and akmod-nvidia-290.10-1.fc16.4.x86_64 kmod-nvidia-3.2.7-1.fc16.x86_64-290.10-1.fc16.15.x86_64 xorg-x11-drv-nvidia-290.10-1.fc16.x86_64 kmod-nvidia-3.2.3-2.fc16.x86_64-290.10-1.fc16.12.x86_64 kmod-nvidia-3.2.6-3.fc16.x86_64-290.10-1.fc16.14.x86_64 xorg-x11-drv-nvidia-libs-290.10-1.fc16.x86_64 nvidia-xconfig-1.0-11.fc16.x86_64 Should I remove one of them? After we will have clarify this point, I will eventually go into your procedure. But my understanding is that I should start nouveau since there is no xorg.conf, but when I build such a file, then the graphics is wrong!! Thank again for your help. =========================================================================(3) Boot into the new kernel. Since you have just installed it, and since there is no xorg.conf, the nouveau driver should be activated. Maybe it will have problems running on your graphics card (it shouldn't, but...), and maybe you will not have high resolution, or even X might not start at all. That is ok, it doesn't matter, as long as you do the next step.
(4) Run "yum install akmod-nvidia". Let it install. It will provide the nvidia driver matching your new kernel, it will write a new xorg.conf, it will blacklist nouveau and remove it from initrd of your kernel. It might take some time to complete.
(5) Reboot the machine again into the latest kernel. This is necessary in order to change from nouveau to nvidia driver.
If all is well, the nvidia driver should be loaded and X should work perfectly, high resolution and all. If it doesn't work, post the contents of /var/log/Xorg.0.log file back to us, so that we can see why it doesn't work and tell you how to fix it.
I hope this was clear enough. Just follow the steps (1) - (5), and it should start working again.
Note that once you have installed akmod-nvidia, in the future when a new kernel gets installed with an update, everything will happen automatically and you do not need to do anything in order to get the nvidia driver for that new kernel. The above (1)-(5) procedure should be done only once, and after that it will work automatically for every new kernel.
