Still working through the last few IP issues, probably another 3-4 weeks if I had to guess. In the meantime we have an NDA repository set up so development is proceeding under NDA. The only bad news is that getting the R6xx 3d engine running is turning out to be just as big a pain in open source as it was in closed source. We're bringing in more of the people who were involved in the original R6xx bringup and I'm hoping that will help.
