i just scanned the whole /24 here, the MAC addresses NetBSD figures out 
are not known on the net -- so no collisions may occur when it really 
'uses' them. however, it seems it doesn't even get that far.

would it be of any help making the appropriate source more verbose to 
see what happens (or not)?
