After this update I get significantly worse X11 performance on i945gme.
Especially Xft text rendering is painfully slow. The kernel tells me:

But this may be unrelated because the performance issue remains
even with DRI disabled in xorg.conf. I tried to update to the 2.7.0.901
snapshot but this didn't help so I had to downgrade to
xf86-video-intel-2.4.3nb1 and libdrm-2.3.1 to resolve the problem.

Is anyone else experiencing this? Could it be caused by our xorg-server
being too old or should I file a bug upstream?

Kind regards,
