Looks like it. David Hinds (who maintains the Linux driver) just sent
me the specs for the D-Link DL10019C chip used in (older?) revisions
of this card (and some others). In the intro it says:
DL10019C is a high performance single chip Ethernet controller
ASIC. It is designed specially for the implementation of a 100M/10M
Ethernet PCMCIA/ISA-PnP compatible Ethernet NIC. It contains a
patented protocol circuit that handles the functions of IEEE 802.3
standard and a host interface circuit. All glue circuits are
included into the chip. For 10M application, DL10019C can be
connected to AT&T's T7213 DISC , NS's DP83910 SNI or AMD's Am7992 SIA
directly, and all frontend transceivers which support MII (Media
Independent Interface) such as NS's DP83840, MicroLinear's ML6692
TDK's 78Q2120, ICS's ICS1890 and Level-One's LXT970, can be connected
to DL10019C for 100M implementation directly.
Sadly, the information on the newer chip (DL10022) apparently comes
from disassembling a DOS driver...
