How to make a clean transition to KWlan?

openSuse 11.0 on a Thinkpad 600E, KDE 3.5 desktop.

I have my Atheros-based Orinoco WiFi card working fine with WPA on my home network, using ndiswrapper, wpa_supplicant, NetworkManager and KNetworkManager.

I’d like to use KWlan to manage the WiFi so I can switch networks, but since wpa_supplicant is already running, KWlan won’t allow WPA configuration (or much else it seems).

I’m sure if I started hacking around disabling or uninstalling things I could eventually get it going, but is there a well-defined procedure for getting my system into the state KWlan wants to be in for initial setup?
