I checked the nvenet.kext plist and it seems to be made to work with any nForce Ethernet controller, from what I understand all of nForce Ethernet controllers are standard no matter what specific Realtek chipset they use. Like I said the vanilla nvenet.kext detects the network card in my board (630i MCP73) but I dont have anything connected on the the card so I dont know if it really works. Do you have troubles getting the card detected or the network working?
As for the other drivers, I cant tell what drivers you could need without knowing what you have installed and what troubles you had as I dont have that chipset. The 6150SE I think its not supported by OS X at all, being an Shared Memory card.
