I have a t42 and atheros card and it works fine w/o the NOAUTO setting 
and WPA (not WEP).   If removing NOAUTO fixes things then maybe some 
fixup is required in the rc.resume script.  I'd have expected devd to be 
notified on resume to bring the interface back up but since you've got 
NOAUTO set perhaps that's disabling it from happening.
