With rt2x00-2.0.14 my laptop freezes instantly when I start wpa_supplicant:

root@jan ~ # wpa_supplicant -dd -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
Initializing interface 'wlan0' conf '/etc/wpa_supplicant.conf' driver 'wext' ctrl_interface 'N/A' bridge 'N/A'

I tried rt2x00-2.1.0 (from 2.6.24-zen3) and got a little further (logs attached). It doesn't freeze anymore but still segfaults.

rt2x00-2.1.0 is broken, please try 2.1.2 which contains many fixes for (among others) segmentation faults.
