This would be nice, yes.

I'd like to point out that AC'97 is a spec for the *back-end* A/D
engine and the interface that the actual audio chip uses to talk to
it. Thus, while we do have some generic AC'97 code, it's not as much
of a leg up as people sometimes seem to think - you still have to deal
with setting up the front-end chip: interrupts, DMA, programming the
sample rate converter, and other front-end-specific goo. The AC'97
support lets you get the mixer code for cheap, but not much else.
