Looks like the kernel couldn't communicate with the chip at all, all reads
just fail. I've pushed out a for-angela branch to my kernel playground at

http://cgit.freedesktop.org/~danvet/drm

Which contains recent drm-intel-next-queued with rc3 merged. That one
boots at least correctly here. Although your merge resolution looks
correct, so I have no idea what exactly went wrong.
