dmesg booting with 2 monitors plugged patch applyed on top of drm-fixes-3.6
drm.debug=4

With the additional patch, I get the DVI screen displaying things when both a
plugged-in but the VGA one now says there is no signal (instead of staying
black). So the behavior is somewhat similar to the vanilla kernel in that
regard.

Booting with the VGA unplugged and plugging it later gives the same behavior as
without that patch (i.e. better than the vanilla kernel).

Attached is the dmesg | grep -e drm -e radeon when the 2 screens are plugged
and the VGA says no signal.
