It's a single-processor (Athlon, socket A) board with the following onboard:

Realtek 8100C 10/100 Ethernet
Realtek ALC650 or 655 (not sure) AC97 Audio

These two components are the ones I'm primarily wondering about. Does anyone
have any experience with either, or this board specifically, with NetBSD?
The rlk manpage says the 8100 is supported, so it should work, but I really
have no idea about the AC97. Will auvia drive it despite the fact that it's
not on a VIA board? If not, what can I do?
