Yes, and I found it.  There was a second instance of network_interfaces 
farther down in the /etc/rc.conf file.  It only listed the bge0 interface, 
and I'm certain it's being installed by a port.  I found the same problem 
on three boxes but not on two others.  I'm looking for the cause of the 
problem now.
