I think the Alsa driver can work on other chipsets. I don't know if
someone is working on it for dmasound, I don't think so.
On these (awacs, burgundy), I think you don't have to register a second
interrupt, the main chip interrupt will be called when the jack state
changes, you can probably act from there. A good source of info is the
darwin source code which contains source code for all of Apple sound
drivers.
Ben.
