This problem may well exist on the GTA02 as well (although it has a 
deeper FIFO, I suspect that will only serve to mask the problem so that 
in accordance with Murphy's law, it will happen only when correct 
operation is most needed).  Does the fact that the GTA02 already uses 
the FIQ preclude this solution for that device as well, or is there some 
other consideration for shared FIQ use?
