A too old firmware might be the problem. If you have a try with kismet 
and the problem is still there, then upgrading the firmware could solve 
it. At linux.junsun.net/intersil-prism is a good explanation on how to 
do this and where to get firmware files.

$ hostap_diag -p INTERFACE

tells you which firmware is currently used (sorry if I'm telling you old 
stuff ;) )

If the sniffing works with kismet then I guess it depends on how you set 
the card into monitor mode.

hopefully it helps you, but maybe someone has experienced similar 
problems and knows more about that.
