Well, I've read up on it, and it requires some work on your part (compiling things, editing critical files). You need to grab orinoco_cs, and build it. Once this is done, first copy the built orinoco_cs.o to

/lib/modules/[kernel version num]/drivers/net/pcmcia/
and
/lib/modules/[kernel version num]/pcmcia

Once the files are in those places, open /etc/pcmcia/config, and add this at the top:

device "orinoco_cs"
class "network" module "orinoco_cs"

Next, go down to the card entry called
"Intersil PRISM2 11 Mbps Wireless Adapter"

Then replace the bind "wvlan_cs" with bind "orinoco_cs"

If things work right, you should see the adapter light up. It is now usable at this moment, but if you want to do anything useful, I'd look around in the forums on how to do everything else.
