I removed the card reset after setting a WEP key and after enabling/disabling encryption. (This is necessary because a card reset forces the card to reassociate with the access point, which restarts the 1x authentication protocol.) The driver works now with the 1x client 'xsupplicant'. A patch is attached.

This depends on AP implementation.. If I remember correctly, I modified hostapd not to re-start 802.1X on new association. I think that Port0 reset was required to take the new keys into use for firmware-based encryption. Does it work without the reset? However, if host-based encryption is used, that reset is certainly not needed for key change (but is probably needed when the keys are set for the first time) and I would agree on removing it in that case.
