Wireless devices also have access to random processes unique to the 
wireless medium.  Things like or RSSI, or perhaps some other low level 
radio related parameters related to fading probably generate a fair 
amount of entropy.  Would that be usable?

Use of WPA would go hand in hand with using the wireless interface.. 
thus generating randomness.  ;-)
