I think that I found the problem. I've filed a PR on this.
/sys/dev/ed/if_ed.c:ed_probe_Novell_generic tries to identify if the
card is NE2000, NE1000, or Linksys by writing a test pattern into
the card's memory at 8k. This fails for the V2 version of the
Linksys PCMPC100, so ed_get_Linksys doesn't get called to extract
the MAC in the special way needed for the Linksys (DL10019C).
When I change that conditional in if_ed.c to always succeed (not a
real fix, but...),

ed_pio_readmem(sc, 8192, test_buffer, sizeof(test_pattern));
! if (bcmp(test_pattern, test_buffer, sizeof(test_pattern)) == 0) {
/* could be either an NE1000 or a Linksys ethernet controller */
linksys = ed_get_Linksys(sc);
if (linksys) {

linksys = ed_get_Linksys(sc);

=================================================================
the correct MAC address is now extracted and the card is correctly
identified as a "Linksys" instead of a "NE2000".
ed0: address 00:e0:98:80:15:df, type Linksys (16 bit)
