The SMC CardBus adapter is known to work.
They sent me one to test with.

You are correct.  The driver is reading the EEPROM incorrectly.  That not
only causes an incorrect station address, it means that the media selection
table isn't read either.  The driver can make a reasonable attempt when
using cards with MII transceivers, but 21143 cards using SYM transceivers
usually have to have the media table exactly right.

The tulip-diag program uses EEPROM read code very similar to what is in my
orginal driver versions..

That looks normal.  It's even a regular-sized EEPROM.

Bad.. that usually indicates a media selection problem.

I'm certain that v92, with no external modifications, works -- I just tested
it.
