I am using a GLX compositing manager, and while I have managed to get
decent performance out of it, when I scroll in Firefox, if I'm playing
any music it skips rather badly. I suspect that the aiglx-zero-copy-tfp
patches could help with this, however...

I am having trouble with these patches. What versions of xf86-video-ati,
xorg-server, and mesa are they expected to apply to? I have apt-get
source'd the latest packages from Debian (xorg-server 1.2.99.905; mesa
6.5.2; xf86-video-ati 6.6.191) and there are a number of rejects in both
xorg-server and mesa. While mesa builds successfully after
hand-application of the rejected patches, xorg-server fails to build:
