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.

http://www.kerneloops.org/oops.php?number=207353

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.
