	That's why I said from the beggining it depend on the
definition of 'work'. For various reasons, I tend to have multiple
802.11 cards in my boxes, in different Pcmcia slots, and it work.
	This is the iwconfig output from one of my box :

# iwconfig
lo        no wireless extensions.

eth4      no wireless extensions.

eth2      no wireless extensions.

	As you can see, I get lot's of retries, but it work ;-)
