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 ... Soeren
