I am actively working on the Tulip driver.
I've been spending about three hours a day over the past week on it, and
I've sent out various private snapshots to individuals to test.

AFAIK, the current public test release, 90K, should work with both
versions of the Linksys CardBus card (at the expense of breaking PCI
21143-TD/PD boards:-<).

[[ My latest snapshot now works with the PNIC-II, but I just borrowed an
AmbiCom CardBus w/SYM transceiver and an ASIX88140 PCI card last night that
reportedly fail with the current driver.  Just when I thought I was ready
for a release... ]]

With Autonegotiation?

Without Autonegotiation e.g. a simple old-technology repeater?

It depends on the version.  The older card works fine, as long as snooze mode
is never enabled.
The new 21143-TD chip has a different EEPROM size and must have burst mode
disabled to work.
