Yea I don't know either since I don't have an Nvidia spec laying around in
front of me!  What I would do is cross reference the PCI BoardId in the
Linux SATA NV chipset driver and see if its supported.  If so, there is a
good chance that by adding the proper PCI information the ata infrastructure
would just take over.   Again, I don't know the exact MCP this motherboard
is using.
