a) I didn't have that before - did kmod-nvidia handle loading the correct
one *without* an
xorg.conf?
b) Do you think it'll do the right thing - this *is* a headless server.
And a general question: what *does* kmod-nvidia do - is it different than,
say, setting up a flag, or a script to notice that you're booting a new
kernel, and run the proprietary installer -a -s?
