While this will allow most R5xx users to already move away from shadowFB, it is still not as fast as it could be :) For instance, EXA doesn't have accelerated (DMAed) up or download yet, but i hope to make this happen soon.
I would like some PPC users to give both XAA and EXA a thorough try. I expect at least exa to be broken, as the prepare/finishAccess hooks probably need to have their surface offset.
So please give it a spin, and report problems asap :)
