cp /usr/src/linux/.config /usr/src/  # preserve the configuration
cd /usr/src/linux/
make mrproper     # this puts the kernel source tree in a state as if it
was just extracted
cp /usr/src/.config .   # restore the configuration
make && make modules_install

Then do what you do to install your new kernel. For example I have 2
boot entries:

- "Gentoo" (default after 5 seconds) with kernel "/boot/bzImage"
- "Test"   with kernel "/boot/bzTest"

So the commands in my case are:

cp /usr/src/linux/arch/x86_64/boot/bzImage /boot/bzTest
cp System.map /boot
lilo

When I compile a new kernel, I first try it with "Test" and if it works,
a do
cp /boot/bzTest /boot/bzImage && lilo  # to make it default boot option


After you are ready with the new kernel and it boots OK (no module
problems etc.) you'll have to emerge nvidia-drivers...again.


In fewer words: Recompile the kernel to solve its problems and then
emerge nvidia-drivers.
