I think the next step is to use Xinchao's patch as-is and get the audio
side going. Once we have that fixed up, we can revisit the interface and
make it solid. But for now trying to polish this relatively simple part
seems like wasted time.

Also, reviewing an interface is much easier if we have both the i915
pieces (already here) and the audio pieces (which I haven't seen yet)
avaialble.

Cheers, Daniel
