ATI R300/400 EXA Render Accel Added

Alex Deucher has announced that he has added initial EXA Render Accel for R300/400 graphics cards to the open-source xf86-video-ati driver. Initially this work only supports transforms for rotation, with no blending support yet. Eventually, this will also be something of benefit for R500 (Radeon X1000) owners as well. This latest code can be found in the xf86-video-ati git tree at FreeDesktop.org. If you run into any problems with this driver, be sure to report them on the Radeon IRC channel. Props go out to Alex, Wolke Liu, and David Airlie for this R300/400 EXA Render Accel work.
