Dear Andrew.
I also had no success with the nve-NIC on my A8N-SLI Deluxe since the 
adaptor stops working when linked up. At the moment I have no equipment 
testing this again, since the machine moved from my lab to my home.
This is what dmesg tells me about the nve0 NIC, maybe this is of your 

nve0: <NVIDIA nForce MCP9 Networking Adapter> port 0xb000-0xb007 mem 
0xda000000-0xda000fff irq 23 at device 10.0 on pci0
nve0: Ethernet address 00:11:d8:92:a3:15
miibus1: <MII bus> on nve0
ukphy0: <Generic IEEE 802.3u media interface> on miibus1
ukphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 
1000baseT-FDX, auto
nve0: Ethernet address: 00:11:d8:92:a3:15

The also on-board sk0 adaptor works well and is NOT GIANT LOCKED.
