Sun U20 supported, fully/partially working... or not at all?

Onboard Ethernet should work. It is just plain NForce4 Ethernet. I haven't 
tested it on this mobo, but on a Tyan S2895. On this machine nve does work - 
as long I don't have memory beneath 4GB. I have to clip the kernel to a 
maximum of 4GB (via MAXMEM config variable), otherwise nve doesn't work at 
all. With this workaround I can usually transfer some 100 GBytes before nve 
problems come up again.

I don't think so. But I don't know if and how Sun customized the standard 
S2865 BIOS.

nve is unstable not only with GigE, but (at least for me) also with only 100Mb
