FWIW, I've never been able to figure out a way to shut it off in the 
legacy drivers. Unless there's some mechanism I've missed, I would 
consider this a bug, but its a hardware bug because - in the rt2500 
driver at least - even disabling it in the interrupt mask register has 
no effect.

I think it would be more accurately termed a target beacon 
transmission time interrupt. The rt61 driver's ISR simply does not 
test for the condition. The rt2400 and rt2500 drivers do nothing if 
not in adhoc mode. If in adhoc mode, they both assume a beacon frame 
is ready to go and send it. This relies on a canned frame that is set 
up during initialization.

Hope this is helpful,
