Currently the OMS boards must be polled in order to provide dynamic motor 
position readback. This would make using the 'operation complete' 
interrupt redundant. The (as yet unavailable) OMS VME58 controller places
the current motor position in dual ported RAM. The driver for this board
could make effective use of the interrupt capability.
