Ignore that, that was with the 6.x driver. I'm now running the patches mentioned in comment 14 and comment 15. With agpmode=-1, and it's stable (2x glxgears, firefox, switching and flicking windows, no sweat), and all the colors distortions are fixed, even on pure X widgets.

Has been running stable for 20 minutes now.

Hooray!
