Xorg crash log

Can't start the X-Server with that commit applied, instant crash.

The 3.11 i915 DRM driver changed the handling of available outputs, on 3.10 I'd
get something (harmless) like "more than 8 outputs detected", which on 3.11 is
gone. Maybe that has something to do with it?

xorg-git
Haswell 4770 (only iGPU)
Linux 3.11-rc7
