	Yes, I know about those devices. I spent the week hacking on
something similar (Linksys WMP11).
	Note that it's quite different from the Mini-PCI available on
Dell laptops. I've also heard that the Mini-PCI Wireless of HP laptops
was USB based. They really want to make our life simple ;-)

	You have two choice :
	1) You use the latest linux-wlan-ng from Absoval (see Wireless
LAN Howto) which support this device.
	2) You ask me for my *experimental* version of the
orinoco/hermes driver that may or may not work.

	For me, both solutions don't work. With both drivers, every
time I read a buffer out of the card, it's corrupted. I suspect it's
because my PC is too old or something weird.

	Have fun...
