This may seem a little vague, but:

When I brought my Q700 with onboard ethernet running NetBSD -current into 
work to hook it up to the ethernet, we did "ifconfig -a" at the prompt to 
see if we had ae0 or sn0.  That lists all available devices.  It will 
list a "sn0 <garbage address>" of your ether card, if you are using sn0.

I don't know the results if you are using ae0, however.  Someone should 
confirm.
