I have been trying to get reproduce the bug to capture dmesg,
i915_error_state and even backtraces from my gdm session, but I am not
sure what triggers it yet.

So far, it seems that it freezes when the screensaver was running for
some time BECAUSE IT HAD TURNED MY SCREEN OFF due to energy policy...

I had since disengaged the energy control option to never turn my screen
off again, so far it has not frozen my system again. I suspect that this
could be the root cause, but I am not sure how to prove it, or what
packages could be involved to further the investigation.

It also seems to happen only on my systems with intel video boards
(Mobile GM965/GL960 Lenovo Laptop and Mobile 945GME Express Asus
netbook).
