The xircom cards aren't multifunction cards. They have an ethernet
chip sitting *behind* the serial interface. The combo cards actually
identify themselves exclusively as serial ports in the CIS.
The discussion about the product IDs is all wrong. The xircom cards
actually have their product IDs in the wrong bytes of the CIS.
0x110a and 0x110b are actually the cards capabilities not the
product ID. No point modifying pcmciavars.h, it isn't used for matching.
BTW, thanks for the tip about disabling the com* at pcmica* to get
the card to work. Can anyone else verify this?
