The nvidia driver in not bundled with the kernel, it is an external third- party module. You need to set /usr/src/linux to point to the kernel(s) you intend to run, and emerge nvidia-drivers for each one. Then modprobe -r nvidia ; modprobe nvidia and restart X module-rebuild is a great tool for this. It knows what out-of-tree modules you use and the ebuilds that install them, and remembers the list (because the time will come when you forget and pull your hair out before you remember) -- alan dot mckinnon at gmail dot com
