I tested the 2.6.38-rc1 kernel with a mesa snapshot, and snapshot of the xf86-video-ati drivers on a ATI Radeon X800XL and the performance for the gallium is about half of what the gallium performance for the X1800XT card. Essentially the card performs according to what I would expect for its class. I did enjoy the performance boost because from the 2.6.37 kernel and the mesa-7.10 the performance in some tasks doubled. For all tasks the performance has increased substantially having the page-flip. Nexius doesn't render correctly though and there are other regressions and so I'll wait until mesa-7.11 is released.
