Cisco Compatible extensions (CCX) driver for MDA vario ?

[A2Z]

I am trying to hook up my MDA Vario to our office Wifi network. We are using WPA/TKIP with LEAP authentication so the standard MDA WLAN driver can't handle that. Does anyone know of a Cisco CCX certified driver ( preferably opensource or shareware ) that has support for CCX 2, 3 or 4 ?
I found and tried SecureW2 but it failed to work.
Here is the list of features I am refering to:

It's not shareware, but I've used the Funk Odssey PPC client with much success on Cisco WiFi hardware in our corporate environment. It supports LEAP, WPA/TKIP etc and Token authenication (i.e. SecureID).

Hope this helps.
