By the way, the same problem occurs with the ubuntu amd64 image from 20081022.1. Just to make sure the network controllers aren't being detected, here's the output of "ip link show" on the server:
1: lo: <LOOPBACK> mtu 16436 qdisc noop link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
So, the network interfaces are really not being detected. After I try to modprobe e1000 and e1000e, the above output still doesn't change.
