It's a modesetting issue, so it will be useful to check on current bits and attach a dmesg with drm.debug=4
That looks very much like the bug fixed with: commit 897493504addc5609f04a2c4f73c37ab972c29b2 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Sep 12 18:25:19 2010 +0100 drm/i915: Ensure that the crtcinfo is populated during mode_fixup() This should fix the mysterious mode setting failures reported during boot up and after resume, generally for i8xx class machines.
