If you don't mind, I'd like to make a couple comments about this. The
first is that the system message buffer often gets overwritten during
the uptime of a system. For instance, I've got a few lines of:

nfs server 192.168.0.7:/usr/pkgsrc: not responding
nfs server 192.168.0.7:/usr/pkgsrc: is alive again

in my buffer. If I got a lot more of those messages, the hardware probe
info that you expect to find would be pushed off. So instead of "dmesg |
grep" you ought to just grep /var/run/dmesg.boot.

The second thing is that ifconfig presents the information in a much
nicer way. Something like "ifconfig <interface> | awk '/address:/ {print
$2}' would work nicely.

Happy MAC address retrieving!
