IO/Drivers/Audio/AppleOnboardAudio .

One problem we'll have is that Apple has three drivers for what we are
trying to use the awacs one for. I think we'll need to split it.

Two points:

1) you were talking about porting a Linux driver, and you're worried about
the APSL? :-) APSL technically can go in a kernel we redistribute (though
it's not certain if we want to), GPL can't.

2) You don't port the driver, you use it as documentation as to how the
hardware works. You write ALL the code yourself (no copy & paste). It's
probably appropriate to say you used it as a resource.

Take care,
