Both the Xircom Ethernet II w/modem and Xircom Ethernet II
(w/out modem) show themselves as X3201.  But the card without
the modem doesn't work.  dc_mii_readreg() always reads 0
whenever called.  There doesn't seem to be any MII device
out there (well, responding).

Here's some debug info.  I added a printf in if_dc.c:736:

	if (ack)
+{
+printf("dc_mii_readreg: ack ok, read %d\n", frame->mii_data);
		return (1);
+}
