Hm.  Interseting.  ifconfig only prints out the status of one medium.

Yes, that's pretty much what I expected.

I think what's happening is that the hme has two separate media interfaces,
only one of which can be in use at a time.  A bit needs to be set to
select between the two of them, and that bit is set based on a probe that
determines the presence of the media rather than the presence of a carrier
on the media.  The NetBSD media framework really isn't set up for this sort of
situation, so it doesn't do a good job in selecting between the two
interfaces.  

Have you tried explicitly setting the media instance with the `ifconfig ... 
instance' command?
