That's pretty bogus. It used to be Boca that had problems with uniqueness
of the the station address.
This is likely a one-time problem with the batch of EEPROMs and probably
some incorrect timing on the EEPROM writing program.
What chip does the card use? With some chips you can write anything in the
EEPROM, while other chips have hardware that limits EEPROM updates to the
address and IRQ info.

You have some sort of IRQ problem.

What documentation has this syntax? I know that Linuxconf gets it wrong as
well..
The proper syntax is
io=0x300,0x320 irq=5,3
