Xorg.0.log

Description of problem:
The server intermittently crashes leaving the following error on
the console:

	(EE) open /dev/fb0: No such file or directory
	E: main.c: Daemon startup failed

	Fatal server error:
	Detected GPU lockup

I'm not sure if the first two lines are from the time of the crash or
from earlier, but I've included them just in case.


Version-Release number of selected component (if applicable):
xorg-x11-drv-nouveau-0.0.12-40.20090528git0c17b87.fc11.x86_64


How reproducible:

Additional info:
Each time this has happened, I've been away from my desk and xscreensaver
has been active. I don't know if this is coincidence, or if something in
one of the screensavers is a trigger.
