As a null data-point, yes. My interpretation is then back towards a
relocation/mm issue. (There is an outside chance that some of the surface
alignment tweaks help, for which getting the SURFACE_STATE would have been
useful...)

Norbert, a quick scan of the bug report doesn't yield any information as to
whether you tested the mb() theory. Can you please try:

http://cgit.freedesktop.org/~ickle/linux-2.6 #master

Just compile the master branch (at 3.7-rc4).
