For those interested: Using this version of xf86-video-ati with r600g on Evergreen = Second Life and Savage 2 mostly work. SL crashes with shaders enabled, but they are optional, and not a big part of the experience. Performance is great. Savage 2 performance is also good, but character models are pretty hilariously screwed up. Everything else about the environment is ok. To get the most out of this you need the latest 2.6.38 prerelease and mesa from git master.
