Bug#622308: xserver-xorg-video-intel: sporadic graphics corruption after upgrade to 2.6.38

[Bill Brelsford <wb@k2di.net>]

FWIW, I've had similar problems since upgrading to kernel 2.6.38,
both on unstable with x-x-v-i 2:2.15.0-3 and testing with
2:2.13.0-6.  The symptom is freezing of most keypresses and
mouseclicks until focus is moved to another window.  The recent
unstable kernel upgrade to 2.6.39-1 helps somewhat -- now get
mostly corrupted or missing text and flickering.

Hardware is an Asus laptop with 965GM chipset.
