Thanks Mike. I pulled out the PHY-dependancies in the fs-enet code and
I'm *almost* there!

Here's the relevant boot output with some additional debug:

fs_init(): start
fs_enet_probe() start
fs_enet_get_stats() start

As you can see from the above, the NFS client tries to contact the
server on the lo interface rather than eth0.

This is despite IP-Config reporting 'Complete' for eth0.

If I set the Gateway parameter for the NFS client to 192.168.1.133 I get this:

fs_init(): start
fs_enet_probe() start
fs_enet_get_stats() start
eth0: fs_enet: 7e:13:12:53:a1:75

IP-Config: Gateway not on directly connected network.

-IP-Config complains the Gateway (192.168.1.133) is not on a
directly-connected network, even though the IP address of eth0 is
192.168.1.75/24.

So this implies eth0 is not 100% up.

Would someone be able to suggest why this is so? What else could I do
to check the state of eth0?

Cheers,
Daniel
