No I didn't. The intel tree is in the same state as Airle's tree (the
magic of git cherry told me so). So here is the attached full Xorg.log.0
for that tree with UXA enabled. The tiling errors are different but
the result is the same. Very poor 3D performance.

I stand ready to try any suggested patches.

Is it likely that the tiling stuff is responsible for the poor
performance or could it be a red hearing? I can have a poke around in
the code and see if anything stands out although reading the
xf86-intel-driver code tree I can see the error message but not by
what interface the request to the kernel is made.
