Did you use an unmodified tulip driver?
Or a version where someone else added an entry.
I don't see how my driver release would have misdetected this as
a 21143 instead of the Comet.

This is in the driver.  It maps to an Abocom design with a ADMtek
Centaur-C/Comet chip.

This ID was not in the driver -- I just added it.

Bogus.

Even more bogus.

It's a D-Link PCI ID, with an Abocom (www.Abocom.com.tw) CardBus ID.

The card loads its PCI ID from the configuration EEPROM.
There is nothing hard-wired that identifies the chip.

Pass "-eee" to the see the text in the CIS table.
