as far as i have read the patch you are still missing some quite
essential stuff. The generic hdmi stuff is not only for the
encoder/transmitter setup, but also for audio clock recovery and feeding
the television with the right audio parameters (sampling rate, bit per
sampel etc.).

I always wondered when somebody starts to port this over to radeon. I
considered doing it myself, but as far as i know the radeon driver it's
relying complete on atombios to do the tmdsa and lvtma transmitter
setup, and at least for hdmi support that's bad. 

I fought quite allot with radeonhd to get atombios+hdmi support running
at the same time, for RV630 i reverted to move setting a missing bit
with the TMDSA and LVTMA control register to the hdmi enabling function,
but i couldn't find a good solution for my RS780 (with DIG interface).

Maybe i am just not feeding the right values to atombios so it can set
the registers right, but since even fglrx revert to programming the
registers directly i assume that atombios is simply not capable of doing
this.

Beside from that i don't have time to support another implementation of
this stuff, so i am sorry but at least i can't take it over.

Bye,
Christian.
