akmod Nvidia dependencies

[Tom Horsley]

If you don't give it time to recompile the driver
after the yum update and before a reboot, things
can be in a confusing state and it won't recompile
after the boot. (At least that is what I have
observed).

I always run "top" after a yum update and wait till
all the compilation and rpm activity disappears before
I type "reboot".

If you install akmod-nvidia again, it will probably
update the driver at that time and you'll be back
to normal.
