Inside Mac does NOT have the solution.  In the recent versions of the Software
Supplement, there is a Restart procedure that does just what you want.  To
use this method from 68000 ML this is the necessary magic code:

		MOVE.L	ROMStart,A0	; (ROMStart=$2AE)
		ADD.W	#10,A0		; (decimal 10, hex $A)
		JMP	(A0)

Since it is OK'd by Apple, I assume this code will work on all existing and
future "Macintoshes" including the XL.
