Is there an entry in the device file for the network boards? The serial ports are a special case. Don't ask me why :) In most other cases they should match up (sound cards are another exception). I assume by 'device file' you mean /dev. NICs aren't devices in the regular context, they're interfaces used exclusively by the networking software. Having a 'direct-access' device in /dev doesn't really work for network cards, so they don't have /dev entries.
