Tried upgrading to 2.6.36-020636-generic, and adding to my xorg.conf:
Section "Device"
Identifier "Intel"
Driver "intel"
EndSection
No luck.
HOWEVER: When also disabling polling by echo N | sudo tee /sys/module/drm_kms_helper/parameters/poll, it seems the problems went away.
So, for those of you still haven't got it right, try upgrading to a fairly recent 2.6.36, disable the polling, and explicitly ask for the Intel-driver. Good luck!
