I think you lack some knowledge on kernel configuration, compilation and installation. Therefore, I would recommend to read Linux Kernel in a Nutshell, written by Greg KH. Printed copies are available from every good on-line book store. Electronic copies are also freely available online, at http://www.kroah.com/lkn/. If you're doing native compilation (i.e compile a kernel for your workstation), then after the compilation, run: make modules_install This will automatically install all kernel modules in /lib/modules/<kernel-version>/, and run "depmod -a" which will create a few text files needed by modprobe to get the dependency resolution system to work properly. If when running "modprobe foo", module foo is not found, it's because the module hasn't been installed in /lib/modules/<kernel-version>/. But again, please read Linux Kernel in a Nutshell, or at least the relevant parts of it, to at least get a basic understanding of what's going on.
