MCP51 Ethernet Controller works with nvnet. I had to borrow a PCI ethernet card before the Debian Etch installer would work. I also had to do "modprobe sata_nv" because the installer couldn't work it out by itself.
I got sound working (just about) using drivers downloaded from the Realtek web-site.
For graphics (GeForce 6100 motherboard graphics - not sure where listed above) I'm using the nvidia proprietary driver, which works well.
Nice board, but a bit too new for easy Linux installation as of Jan 2006.
