Yes, I got that.  Sorry, I guess I should have explained my thinking in
a little more detail.

Your problem appears to be due to a GPU lockup.  In your case, the X
server apparently detects the problem and aborts, rather than itself
freezing.  But the underlying problem, the thing that will need to get
fixed, appears to be the same.

Agreed.  The X/Troubleshooting/Freeze page has a section on "Reporting
GPU lockup Bugs".  So in additional to the information you've already
provided, you'll want to collect the dmesg log (check in /var/log),
information about your video card (though I suppose you could just
attach the Xorg.log.old, as that would have the hardware info), and what
desktop visual effects you have enabled, if any.
