I am using this on an R580. 3D works; I'm using Google Earth and Compiz. Actually, Compiz works much better with the open source radeon driver than it does with fglrx! There's no insane "lag" when maximizing windows or switching desktops, everything is fluid and instant.
Note: be sure to activate EXA though since XAA is the default.
However, Xv is tearing badly (just like with fglrx). Fortunately, Gl video with vsync works.
Wine doesn't work and most "advanced" games don't work either.
