The changes in r2486 made compilation of madwifi with SUPERG_FF=0 (which I use to debug other problems in the driver) impossible due to a reference to a non declared not initialized txq variable in if_ath.c:

Sorry I can't append a proper patch, my knowledge of network queues in the kernel is rather minimal :)
