Need driver that supports WPA

[rookcnu]

I have an HP Ipaq 5455 with Windows Mobile 2003. My employer uses the Odyssey client by Funk for wireless connectivity. Only problem is they use WPA for encryption and HP does not support WPA for this particular device. Is it possible to install a different WLAN driver that supports WPA so I can get on to my employers wireless with my handheld?

Funk does make an Windows Mobile client.
