The rtl8201 is just a transceiver, not the NIC.  You'll need a driver that 
supports the NIC, which is likely a nVidia chipset with a new PCI ID on 
the Ethernet controller.

You'll need to find the PCI ID, then locate the proper driver and version.

In the Scyld cluster system we report this as part of the PXE boot 
sequence, and are in the process of implementing a system that 
automatically reports and updates the driver set.  Rocks isn't that 
sophisticated so you'll need to do it by hand and reinstall the cluster 
for each hardware change.

The reason for this hardware design is that the analog parts of a 
transceiver are much different than the digital parts of the rest of the 
system, so it's best to put them on a chip made using a different process.  
Transceivers have a standardized interface, so the motherboard designers 
picked the least expensive chip.
