I was having the ndiswrapper instead of wext problem as well, with a rt2500 device using ndiswrapper ( The native driver wouldn't associate as well, but that's another issue). I was manually using wpa_supplicant to get around it.
jpierre's packages solved the problem.
Also, ndiswrapper worked for me in OpenSuse 10.1 as well.
