Odd that it should be impossible, I have lots of systems with two wireless
cards and a few with three (although I am in the UK so I have more 
available channels).  I do put a copper tape between the heads of the 
pcmcia cards, but nothing more.  All channels seems to work as you
would expect.  

Still, doing six impossible things before breakfast always was fun.
