You should be fine just installing the kernel images that come with Debian. Unless you're having a problem with those packages, there is no need to build your own kernel. >> If you are trying option 1, using the stock driver in 3.3.5, then you >> should have to do _nothing_ other than upgrade the kernel.

Otherwise, it's likely that there are errors in the system log, if you post them here, we might be able to help you fix them. > so I came up the idea to remove the one in 3.2.5, I didn't realize > it's independent from kernel version until later. > > another reason to remove it from 3.2.5 is to reduce the chance of my / > get saturated. I only give 666M. I'm surprised you are managing to fit an entire Linux system in 666 MB. To re-iterate, I strongly recommend that you install the stock kernel that comes with Debian. There is no need to build your own unless there is a problem with that kernel. To get the firmware for your broadcom wireless card, just install the firmware-b43-installer package and this will automatically install and maintain the latest versions of the firmware for you. b43-fwcutter and the firmware itself are separate from the kernel and there is no need to delete them when upgrading.
