Yep, I'm folding again under the tek_republik user name.  I fired up the latest beta client, and got it going on a couple of 5870s and a 6850.  Find our team here! We are 63 in the world, but come on, we can do better than that people! Version 7 of thye Folding at Home client is nice. I had problems running 6 when I upgraded to 5870s. Find more details about it here. Yes, there needs to be some optimization for the 6000 series. There is supposed to be updated support for the new Radeons coming soon.
