 I'm guessing that revision 1.77 of src/sys/dev/ic/hme.c is to blame here:
 
   http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/ic/hme.c.diff?r1=1.76&r2=1.77
 
   Check for internal PHY first, so that it always attaches first, even when
   we have an MII transeiver attached.
   Count all collision and error counters.
   Handle counter overflow and RXTERR.
 
   Tested on U60 HME, PCI HME (501-5019) and SBus Sunswift (501-2739)
 
 and I guess that the T1 wires up the MII (external) PHY to the physical port.
 If things work with `ifconfig hme0 instance 1`, that will be the case.  The
 problem then becomes how to work out which PHY's are actually connected to a
 physical port, as both PHY's are always present on all the single HME's that
 I've seen.
 
 Thanks,
 
 J
