Change 108060 by mjacob@newisp on 2006/10/18 20:22:46

	Put ISR read arguments for mailbox and semaphore pointers
	back to pointers to shorts.
	
	Reinstate PTISP checking, only set a bit for them in sdparam.
	
	Move some items araound and add a reset0 point to turn intsok
	back to zero.
	
	Put in request queue debug printouts.
