This is somewhat annoying, since PHY chips seem to come in packages even more nasty to deal with than the QFP80/0.65 package that the cpu comes in.
Check ebay and surplus places for old Ethernet interfaces: back in the days when there was still heavy competition between 10BaseT and 10Base2, there were cards with 15-pin D-sub interfaces to an external PHY (although I think they were called something different).
