MPC83xx - 2.6.23, UCC_GETH and NFS Boot

I am attempting to get a new board booted up using NFS root file system.
HW: Board based lightly on the MPC8360E_MDS

I have the kernel 2.6.23-dirty configured to use the Freescale QE driver.
I am using U-boot 1.3.0 and am able to use the Ethernet there, so I know it
is up.

I am using the following bootargs from U-boot.

bootargs=console=ttyS0,115200 root=/dev/nfs rw

I can see during initial kernel load up that it loads:
"ucc_geth: QE UCC Gigabit Ethernet Controller"

However, later IP-Config claims there is no valid Ethernet device

Is there something I have to do specify what type of PHY device I am using? 
Perhaps a National DP8365 is not supported yet? Or perhaps the MDIO driver
in linux is not looking at the correct MDIO address?

In U-boot I am using PHY addr 0x01, could this present a problem?
