Bug#558237: linux-source-2.6.32: X with xserver-xorg-video-intel does not work any longer

[Reinhard Karcher <reinhard.karcher@gmx.net>]

Status update for kernel-image-2.6.32-trunk-amd64:
 
things improved a little bit. Console switching is now possible, but in 
X only a black screen is visible, with the exception of the mouse 
cursor, which is visible and moves as it should.

The following message vanished from Xorg.0.log with the new kernel:

Fatal server error:
Failed to map batchbuffer: Input/output error


Please consult the The X.Org Foundation support
        at http://wiki.x.org
 for help.
Please also check the log file at "/var/log/Xorg.0.log" for additional 
information.

The messages in the calling VT are the same:

../../../libdrm/intel/intel_bufmgr_gem.c:825: Error setting to CPU 
domain 96: Input/output error
../../../libdrm/intel/intel_bufmgr_gem.c:899: Error setting domain 773: 
Input/output error
