Call CEMM v5.10+ entry point with:
	AH = 00h get memory manager's state
	    Return: AH = state
			bit 0: turned OFF
			bit 1: AUTO mode enabled
	AH = 01h set memory manager's state
	    AL = new state (00h ON, 01h OFF, 02h AUTO)
	    Return: CF clear if successful
		    CF set on error
	AH = 02h Weitek coprocessor support
	    AL = subfunction
		00h get Weitek support state
		    Return: AL = status
				bit 0: Weitek coprocessor is present
				bit 1: Weitek support is enabled
		01h turn on Weitek support
		02h turn off Weitek support
	    Return: CF clear if successful
		    CF set on error
			AH = error code (01h invalid subfunc, 02h no Weitek)
	AH = 05h get statistics
	    ???
	AH > 06h
	    Return: CF set
		    AH = 01h (invalid function)
Notes:	AH=03h,04h,06h are NOPs which return CF clear, presumably for backwards
	  compatibility with earlier versions of CEMM
	in v5.11, AH=05h merely prints an error message (using INT 21/AH=09h)
	  stating that a different version of CEMM is installed and it is
	  therefore not possible to display the statistics
