Subject: i915 regression with 3.3-rc3+git

Hello,

i've upgraded from 3.2.0-rc7 to post 3.3.0-rc3 git 
4903062b5485f0e2c286a23b44c9b59d9b017d53, attached you can find dmesg 
with drm.debug=0xfff

This started to appear in logs:

[drm:intel_framebuffer_init] *ERROR* unsupported pixel format

X is getting a wrong resolution (log attached) and there's a lot of 
flickering, if i try to play a video the desktop turns black, the other 
ttys still works fine though.

Please CC me since i'm not subscribed.
