There is now bi-cubic X-Video support for the Radeon R300 and R500 series GPUs, heavy optimizations in the video functions, and lots of code cleaning. The DRI, acceleration state, and CP (Command Processor) work has also been moved into their own code structures. This work came in the form of over two dozen code commits. The PowerPC build process for this ATI driver has also been fixed.
Run git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-ati to see the latest work to this X.Org driver.
