Got video acceleration. Requires kernel 3.2, Gallium3D(both in backports, gallium is built into the xserver update), and DRI2). You can get 2D with a stock install and "radeon" driver and a little 3D. This gives you 3D. For both scenarios, I needed the restricted firmware(stable is fine for "radeon" driver but backported version needed for Gallium3D to make hardware acceleration work with Open source drivers. Not sure if Flash acceleration was working with "radeon" as I only kept it for a bit and the Gallium3D does work with Flash acceleration. Word of warning, a bug with kde and the driver means you better use xrender mode to avoid corruption when going from full screen opengl to the desktop.
A fool thinks they know everything.
A wise person knows enough to know they couldn't possibly know everything.
There are zealots for every OS, like every religion. They do not represent the majority of users for either.
