Same here - madwifi CVS and wpa_supplicant 0.3.6.  I updated madwifi last friday 
  - maybe here is a fix in there.  It used to work last August/early september 
before I did an update.

WPA-PSK AES fails. for me.  Works with driverloader and with windows.

WPA-PSK in all variants fails with Cisco 1x00 APs running the latest IOS SW.  I 
have 802.11g radios.  Are you running IOS or VxWRKs on the 1200's  802.11B, G or A?
