HDMI audio support with radeon driver

is there any WIP on enabling audio output throught HDMI with the radeon driver?
It seems it has been recently implemented in the Linux kernel 2.6.33 [1], but
it's in the KMS driver, so will it need to wait for a KMS implementation on
FreeBSD too? I don't really know how this is supposed to work, but can't it be
just hacked in the snd_hda driver?

I know this is implemented (and working well I suppose) with the radeonhd
driver, but... radeonhd segfaults on my computer, and I need the radeon driver
anyway. :)

For now, when I try to play a video with the HDMI sound output, it plays the
video too fast and with no sound at all, like described here [2]. The snd_hda
driver does strange things.

Anyway, if I can be of any usefulness to have it implemented on FreeBSD, like
for testing it, I will be glad to, of course. :)
