eth0 not detected

I had successfully set up eth0 a few days ago, but it seems to have stopped
working.  I didn't change my configuration; all I've done is use opkg to
update/upgrade.  I'm not sure what changed, but it appears that the
kernel/hald/udevd is not recognizing the device.  Ideas on how to
troubleshoot would be much appreciated.
