Intel driver 2.11.0 + lid close event = GPU freeze

[Łukasz Maśko]

I've just noticed, that whenever I close my laptop's lid, my whole X system 
freezes. I can switch to a console, but restarting X or even rebooting 
computer is not helping, I must turn off the machine and start it again. In 
the log file I'm getting such error:

(EE) intel(0): Failed to submit batch buffer, expect rendering corruption or 
even a frozen display: Input/output error.
(WW) intel(0): i830_uxa_prepare_access: gtt bo map failed: Input/output 
error
(WW) intel(0): i830_uxa_prepare_access: gtt bo map failed: Input/output 
error

I have an Intel 945GM graphics chipset driven by intel driver 2.11.0 and 
kernel 2.6.33.3. I'm still using xserver 1.7.6, because xrandr refuses to 
work correnctly under 1.8.0 for me.

Does anybody now, what may be the problem?
