WRAPs ( supposedly use DP83816. This is
listed on their page

  Connectivity: 	1 to 3 Ethernet channels (National DP83816), ...

and I can confirm that both my boards read DP83816 directly on the chip.
The interfaces come up as

  sip0 at pci0 dev 14 function 0: NatSemi DP83815 10/100 Ethernet, rev 00
