By the way, the -k and -K options to the nvidia installer (one takes
the kernel version as an argument, but I can never remember which) can
be used to only install the kernel module, which will not uninstall it
for previous kernels. Which means should you need to boot an older
kernel, it will work just fine without the script running again and
clobbering the install for the latest kernel. Should also be a little
faster.
Also, is there a command that will tell you if a kernel module exists
without having to look in a specific location? (maybe modinfo?) Might
be better if for some strange reason the kernel module gets moved.
Just some thoughts.
