problems with r197427 (i386) and nvidia driver

[Alexander Best]

ok. this is very odd.

i'm now running r197301. i was running this revision for a week or so and had
no problems with the nvidia driver whatsoever but the problem also exists when
running this revision. so it doesn't seem to be a kernel problem.

i've also re-installed world!

i also noticed that other modules in /boot/modules don't work any longer. the
virtual box driver e.g. loads, but when trying to run a virtual disk vbox
cannot find the kernel module.

the cause for this problem might be some data corruption because i was running
mplayer under X with the nvidia driver working normally. then suddenly the
machine froze. after ~ 2 minutes it automaticcal rebooted. no core dump was
produced though. after the reboot the problem first appeared.

i checked all my harddrives with fsck which revealed no problems.
doing `svn --no-ignore in /usr/src` revealed no problems.

cheers.
