Thanks for your help. I've added the card's id to if_iwn.c and rebuilt
the kernel. When system boots, the card is recognized. But the driver
says it cannot load the firmware for this specific card. I guess more
work is to be done to get this card running.

I took a look at the code in if_iwn.c. It seems it is pretty hard coded
for the known cards. If a new card is to be supported, much work may be
needed to do it.

Anyway, thank you. I think I might need a USB wireless solution now.
