I can confirm a very similar behaviour on a Thinkpad X300 with Intel Corporation Mobile GM965/GL960 graphics. Version of xserver-xorg-video-intel - 2:2.6.3-0ubuntu9.3.
X would crash randomly, though it is more likely to occur when playing videos/DVDs in full screen.
As far as I can tell, there's nothing suspicious in the Xorg.0.log.
The only error (or is it simply a warning?) was a set of two lines similar to the following each time X crashed and restarted:
[10272.357258] [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0
[10272.357505] [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0
Re-creating a "vanilla" xorg.conf did not help... Also I'm using EXA and setting the "ExaOptimizeMigration" option to "off" in my xorg.conf did not help either...
As a side note, in my case at least, it looks related to memory. The problem only shows when *fully* using 4GB of physical memory. If I'm using less than 4GB, for instance by disabling PAE, then video playback (even with recent encrypted DVDs) would run fine...
