I also have a 440GX eval board from IBM. I tried the ocotea config and it boots up just fine.
Great! Good to see some mileage from my port!
However, I get a message about an I2C read error. Is this normal?
Yes, and no :) Normal if you have only one (1) DIMM populated. If there are two (2) DIMMs you _*shouldn't*_ see that message. I don't have another DIMM handy, so I couldn't test that. If the message bothers you that much, you can remove the second SPD_EEPROM address from the config (do this locally though).
In addition, I can't seem to bring up the network.
See below...

Looks like you have one DIMM installed.

There's your problem. Do the following: setenv ethaddr XX:XX:XX:XX:XX:XX setenv eth1addr YY:YY:YY:YY:YY:YY setenv eth2addr ZZ:ZZ:ZZ:ZZ:ZZ:ZZ setenv eth3addr AA:AA:AA:AA:AA:AA
where the 'xx', 'yy', etc are the ethernet mac addresses for your board. (Flip it over, they are on stickers on the bottom of the board).
ipaddr=<ipaddr>
You'll want to set the others as appropriate also...
netmask=<netmask> serverip=<servip> gatewayip=<gwip> hostname=<hostname> netdev=eth0 stdin=serial stdout=serial stderr=serial

Hmmm... since your setup is using EMAC0, ensure you have the cable in port 0. Also, the only enet group supported is group 4, so ensure you have the jumpers set that way. (J79, J80, J29, J31, J76, J81) are all 1-8 and 3-6.Good luck,
