I've got one question for that mailing list. Will that just be about the open source drivers and/or the documentation (release) or will that also cover the fglrx driver (I don't guess it will be a support list for the fglrx driver.)?
Another thing is, I've got the feeling that the bugzilla page could need some serious clean up. As far as I can tell, there are a lot of dups and just about anything is marked critical or blocker.
Maybe you could need some help, I don't mean me, but I'm sure, there are a some guys who know about this hardware and the drivers, that could help out.
