Impossible to start X with 2.6.33rc kernel, because there is nothing on the screen except the cursor. The cursor changes if you get over an icon(or better: the place where it should be).
Switching to tty works.
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
render error detected, EIR: 0x00000000
Compiling 2.6.32.* kernel with exactly the same settings works just fine.
Xorg log, output of dmesg, lspci -vxxx and lsmod and my kernel .config are attached.

Marked as a regression.
This should have been fixed in 2.6.33-rc7 with:

drm/i915: Fix the device info of Pineview
Pineview doesn't has CXSR and need GTT-based hardware status page.
It fixes a X boot hung issue on Pinview since commit cfdf1f
More details in http://bugs.freedesktop.org/show_bug.cgi?id=26439.
Problem is not solved on Kernel 2.6.33-rc7-git2 for me.
Neither can I start X nor am I able to switch to tty after xinit.
There is no cursor anymore, only a black screen.
Loading the i915 module manually causes a segfault.
I will an attachment with dmesg error.

Relevant part of dmesg.
Shaohua, can you take a look?
Wanted to write it yesterday, but there was a mysql problem with filezilla.
Problem fixed in 2.6.33-rc8.
