I've just ran hard into this bug. The machine exhibiting the problem is
a Dell Latitude D505 with an 855GM chip. It may be of interest to note
that I've only encountered this once, and that was _after_ installing
2.6.15-26-686 and the corresponding modules, so I hadn't seen it on the
386 flavored kernel. The kernel is not tainted BTW.

More importantly, I *hadn't* put the system into sleep when this
happened. It was triggered through MPlayer, trying to get a movie with
the XV backend go into fullscreen. The result was a constantly
respawning gdm. I did manage to reboot the system gracefully through an
SSH login.

Still, I plan on using 6.06 for a long time (I used Warty satisfactorily
on this same machine until it was EOL'ed and Breezy came out!), and it
would be quite bad if the X system would go down randomly when something
uses XV, rendering the for me fantastic 3 year desktop support useless
:(.


Anyway, here's the relevant part of the X.org.log file. It's not the original log of the server when it crashed, as it was scribbled over a few times by a continuously respawning GDM.
