The glxgears column is meaningless.

May I quote Gunter Ohrne: glxgear

PAT wasn't supported at all in 2.6.26.
Mh, at least the configuration

kernel?
PAT is disabled in 2.6.29, we feel like it may explain some performance
problems if the video memory isn't in write combining anymore.

Mh, I just checked my 2.6.26's image configuration, and it also seems to
have PAT disabled:
$ uname -a

Hi!
I just upgraded to package version 2:2.7.0-1 with no improvement.
Composite mode with EXA still is unusuably slow.
Can you try without another kernel? Either Debian's old 2.6.26 or a
custom 2.6.29 with PAT enabled.
I still have to check whether XAA works again

Ok, guess what - with Debian's 2.6.26 package it feels quick and snappy.
