Keep in mind, that I am using a dualhead configuration so usually
dri/agp/drm is not used.
However I just tried a single head config and while it is crashing in
agp 4x mode it is working as fast as expected with drm/dri/agp 1x...
However this is of no use for me as I need both heads. But I don't see
why it became so much slower in 2.6.0-test ...
