[CentOS] X just died then restarted

Just had a weird thing happen that I've never encountered before.

Running Centos 5.x (updated) on 32-bit (Athlon XP).

Was going along in Firefox when suddenly my screen went black and the hard
drive light came on mostly steady for several seconds. After a little bit
I got back the X login screen. It normally comes up on F7, but F7 was dead
(with some text I'll paste in below in case it means anything to someone)
and (since I have another dedicated app on F8) it came up on F9.

The last few entries in /var/log/messages, which are about the right
time, are:

Apr 30 18:34:44 hostname restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) No such file or directory 
Apr 30 18:34:52 hostname kernel: NVRM: not using NVAGP, an AGPGART backend is loaded!

and the stuff on the F7 screen is (hard to read and surely incomplete):

So since the stuff from /var/log/messages mentions agpgart and this
stuff from F7 mentions /dev/nvidia, I'm guessing the nvidia drivers had
some kind of brain fart (:) ??

FWIW, I'm running the Nvidia 96.43.01 drivers, direct from Nvidia
and not any repository. 

Any ideas?

Thanks!
