This problem is Network manager related. I don't use Network manager and at home my ssid is hidden. It takes some time, but eventually wpa_supplicant can connect without any problem. This is with module 1.1.17kds from the 2.6.24-5 modules, and at http://www.linuxwireless.org/en/users/Download there is a newer version. With that module version, 1.2.26k, it works just fine. Scanning however doesn't if you use 'iwlist scan'. Scan results from wpa_supplicant do work.

Note:
Module 1.2.0 never worked for me.
