Hello,
I'm currently testing kernel 2.6.32-rc1 and the first thing I noticed is:

[drm] Enabling audio support

..that, and 10 wakeup/s ;-) I'd like to share a couple comments:

- first of all, I have a M56 (RV630) which lacks the PCI audio
function, I guess in this case the audio shouldn't be enabled at all
- the r600_audio_update_hdmi callback: is it really necessary to call
it 10 times/sec, even if no audio is playing? In a "normal" audio
driver that would be done only on ALSA ->open (or maybe ->prepare)
functions, but in this case it's not clear to me how the two pieces
(drm and alsa) interacts (can someone point me to the relevant docs?).
Maybe a tighter integration between them is needed?

thanks,
Luca
