Cardbus is simialr to PCI far from trivial to implement. 
USB may be doable but documentation on USB wireless devices may be hard to get. 

Another possibility might be an ethernet interface, plus an off-the-shelf wireless access point. 

I'm sure there must be some OEM wireless modules available - this is probably your best bet.
