Bad 2D performance with intel driver on Mobile GM965/GL960

Hmm, I guess 11.1 uses intel-2.5, which has (at leat on my 945GM)
quite a number of performance problems.
Xorg-7.3 (xserver 1.5.x) also has quite a bad performance bug for
dixLookupPrivate which will only be fixed for 1.6 because of API

If you don't use a xrender-based composition manager, reverting to XAA
could probably help:
