AMD/ATI really needs to get their act together in the next driver release and provide something along these lines or at least confirm that a working UVD2 solution is really in the pipeline or Nvidia will snatch much of the Linux HTPC momentum, mind share and development for the next few months or so.
C'mon AMD! Publish all that R600/R700 documentation and show people how these features can find their way into the Free drivers anytime soon or it'll be difficult for most off us to see how you could possibly provide a more appealing solution than Nvidia's (given what we are used to have to endure running the fglrx driver).
ATI needs to get their collective rear in gear, or my next gpu will be nvidia.
ATI has hardware superiority and pricepoint superiority at present (at least, in my price range), but if I can't effective use my card, it matters little. I want to see XvBA working, and dri2 integrated into the proprietary drivers (and timely updates for new xservers/kernels). I also want to see working open-source drivers (with KMS, gem, and dri2, and hopefully video acceleration using extended XvMC or, even better, VAAPI)
