None at all and no msgs with MIIVERBOSE or the various GEMDEBUGs.

From what Eduardo mentioned, it's not supposed to have a phy, because it
definitely has a SERDES, the agilent HDMP-1646A.  Thanks Eduardo.

The doc that i found on the SERDES seems to indicate that all it has is
a loopback pin and is otherwise unconfigurable...but, that doesnt make
sense to me, since something has to perform the negotiation.  clues welcome.

btw, if anyone has a pointer to user docs for the GEM or agilent, please
pass them my way.  My googling has not turned-up anything useful yet.
