Looking for a mainboard

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I'm looking for a mainboard that's currently available and
well-supported by NetBSD-4.0/amd64 (current is fine as well, but 4.0
is preferred).  It should include a supported gigabit network and SATA
controller.

I already have a CPU and RAM:
AMD Athlon 64 X2 4400+ 65nm Socket-AM2 tray, 2x 2.30GHz, 2x 512kB
Cache (ADO4400IAA5DD/ADO4400IAA5DO)
Kingston ValueRAM DIMM Kit 2GB PC2-6400E ECC CL5 (DDR2-800)
(KVR800D2E5K2/2G)

If it's not expensive, so much the better.

Alternatively, please recommend a cheap, known-supported SATA
controller.

Thanks,
 Thomas
