	This would be simply amazing !
	Note that there are two different ways to do scanning with
PrismII firmware, the Information Frame method (implemented in
orinoco.c) and the RID method (implemented in HostAP). On the other
hand, it seems that Lucent firmwares support only the Information
Frame method.
	My Symbol firmwares (regular Pcmcia kind) don't support the
Information Frame method (always return empty info frame), so my guess
is that it's a feature specific to the CF card (or recent firmwares).
	Keep me posted, I'm interested...
