ndiswrapper working but no WPA

Hi,

I'm in the process of getting an ancient Marvell Wireless Adapter working in a dual boot Linux/XP system.

At one point, I couldn't reboot Linux, after a change to /etc/sysconfig/kernel, but I managed to back that change out and I have a booting system.

Once I had the system back, I went into Yast to look at the state of the network adapter. I then had a popup that said something about ndiswrapper, and did I want a Modprobe performed. I replied in the affirmative, and I know have an adapter that knows about my router.

Problem is that I am being offered only LEAP, Dynamic WEP, and WEP in the security dropdown box; no mention of WPA.

Is that something to do with Windows 98 driver I have associated with the adapter or something else?

Thanks
