I have a Digital DE500-AA here which the driver reports uses the DC21140A.
It works fine with 2.2 (but not with 2.1.5).  The only question I have
about it is, is it supposed to auto-detect full duplex 100Mb/s connections?
It reports:

de0 <Digital DC21140A Fast Ethernet> rev 32 int a irq 10 on pci0:8
de0: DE500-AA DC21140A [10-100Mb/s] pass 2.0
de0: address 00:00:f8:01:e7:8f
de0: link up: enabling 100baseTX port

regadless of whether the other end is full or half duplex.  The output
error rate seems higher when the other end is full duplex (BTW, the
other end is a 100TX card in a Cisco Catalyst 3000 switch).
