I'm sorry, but it does not work for me on my Nforce4 based
motherboard running FreeBSD/amd64:

nve0: <NVIDIA nForce MCP9 Networking Adapter> port 0xb400-0xb407 mem 0xfebf9000-0xfebf9fff irq 22 at device 10.0 on pci0
nve0: Ethernet address 00:01:29:f5:6b:91
miibus1: <MII bus> on nve0
ciphy0: <Cicada CS8201 10/100/1000TX PHY> on miibus1
ciphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto
nve0: Ethernet address: 00:01:29:f5:6b:91
nve0: link state changed to DOWN
nve0: link state changed to UP
nve0: device timeout (2)

I'm totally unable to send or receive any traffic under FreeBSD with this
nic.  It doesn't randomly timeout, it never manages to transmit (or receive)

I can provide more details about this board upon request..

The Solaris driver (from http://homepage2.nifty.com/mrym3/taiyodo/eng) uses the
same interface as we do, and uses the same version of the nvidia libs.  It
has been bulletproof for me so far on this same machine when it is booted
into Solaris.
