There seem to be more then one issue. I'm running into one of them here on a Lenovo Thinkpad X200s. It's 2.6.30 and I enabled KMS the first time here. So I can't tell if it is a regression.

Are looking similar to #207353 to me. That's the one I can easily reproduce by booting into an KMS enabled kernel. Without modsetting eveything is fine. Let me know if there are patches I should give a try.
The result is that the EDID data could not be read and the wrong screen size set: [ 45.524589] i2c-adapter i2c-3: unable to read EDID block. [ 45.588200] i915 0000:00:02.0: DVI-D-2: no EDID data [ 45.777251] [drm] TMDS-14: set mode 1360x768 13 [ 45.777261] [drm] TMDS-16: set mode 1360x768 13 <= Should be 1280x900 here
Somehow the driver tries to use DVI1 and DVI2 while the display is connected to LVDS1.
