Orinoco PC Card 802.11b and WPA

I just purchased an Orinoco Client PC Card 802.11b Gold Series from overstock and they said that the card was upgradable to the WPA standard. Well I could find 0 info on the proxim site but did a search and found a pdf doc from proxim saying that it was not going to provide the upgrade to 802.11b devices due to hardware limitations. I find that a load of bull because just about every other 802.11b card I have seen supports wpa.

So basically am I stuck with a wep only card or are there drivers availible for 802.11b devices for WPA that I just cant find.

Thanks
