radeon KMS HDMI for r7xx coming soon

I've just played some music over HDMI using radeon KMS and RV730 card! My local patch rewrites the way we choose HDMI block for encoder, drops current [em]hacks[/em] and make it work on more hardware. Plus of course it adds some single bits for DCE 3.2 GPUs. It needs some cleaning, splitting maybe and fixing resume. I hope to post it in day or two, hopefully in time for getting it into 2.6.34 :)
