The board now at least ARPs through the interface to the NFS server and the NFS server responds. However, that's as far as it gets at this point (see below). Any ideas? In the interim, I'm going to try experimenting with a few more things.

Dear Grant,
Are you sure that the ethernet interrupt are correclty handled? It seems to me that the oak board never answers.
Have you ever serviced correctly a interrupt on the PPC403?
Interrupt handling on the PPC403 is very different from other PPC-architectures. If you have HW-debug possiblity through the JTAG, try to break on external interrupt at address 0x500 and step through the interrupt code to verify that it works correctly.
Other idea: Do you need a byte swapping to set the controller TCP/IP-address/ethernet adresses?
