Thanks for offering to have a look at this.

no change I'm afraid.

when plugging in the Xircom CEM56, the ethernet part
comes up fine and /etc/serial/serial is fed

$1=start, $2=eth0

and then /etc/pcmcia/serial looks for /dev/eth0

here's the output in /var/log/messages following insertion. 
I've added some debugging for my own edification. The 
machine's name is "foghorn".

#net.agent doesn't know what to do with Slackware, so I've rolled my own.
