You have a CardBus card, not a PCMCIA card.  "PCMCIA" refers to 16 bit
cards, while "CardBus" is PCI-like 32 bit cards.  "PC Card" is the
generic name.

0x213 is invalid.  You must mean 0x20d.

Note that this is an old driver version, modified from the original 91g-ppc.

The problem: the EEPROM is missing or unreadable.

You have a MII transceiver, so the card should still work albeit with
the wrong station address.

Except that this driver version picked the wrong transceiver connection!
The real v0.91g would have selected the MII transceiver.
