Your debug kernel 2.6.38-3-generic #30lp714719v201102101355 did freeze once before I had ssh set up. It did not freeze again but dmesg indicates a hang:

 3023.928039] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[ 3023.930371] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 370145 at 370143, next 370146)
[ 3023.930571] [drm:i915_reset] *ERROR* Failed to reset chip.

There doesn't seem to be a lot of extra debug info in dmesg beyond what is in /var/log/kern.log?

When I run 2.6.38-4 the system freezes within a few minutes and I get a similar dmesg:

 1312.444041] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
