Now there are at least three of us who just can't wait to feel the
sweet sorrow of booting tomorrow's broken kernel :p

If you build kernels frequently you don't need to install the entire
nvidia-drivers package each time.  You need only recompile the code
for the nvidia kernel module, so we extract (and save) just that one
part of the code from the source tarball like this:

#cd /usr/src
#sh /usr/portage/distfiles/NVIDIA-Linux-x86_64-295.40.run -x
#mv NVIDIA-Linux-x86_64-295.40/kernel/ .    <--- notice the dot
#rm -rf NVIDIA-Linux-x86_64-295.40/

(the next step is optional, but it will help you next week ;)
#mv kernel nvidia 

A normal person would now do the following:

#cd nvidia
#make module install   //Done!

But you are not a normal person, are we? :p  *You* will get an error
message that your kernel is from another planet and the build will die.

No worries.  The important thing is that the binary blob (nv-kernel.o)
from nvidia.com still works perfectly with today's git kernel.

Confession:  I know this *only* because I convinced the nvidia installer
code that I know more than than the nvidia.com devs know.

Obviously a lie most foul, but it worked again! (This time.)

[I'm falling asleep at the keyboard now and I don't want to give you
bogus information, so I'll be back tomorrow with the rest of it.]
