Using some hints and PCI IDs from the 2.4.20 kernel driver for the
810, I generated the following patch against alsa 0.9.0beta12. It
works on the above mentioned motherboard just fine so far.
But it wouldn't hurt for someone who knows what they're doing to
sanity check it before applying to the source tree.
