	AX = 4F06h
	BL = 02h
	CX = desired scanline width in bytes
Return: AL = 4Fh if function supported
	AH = status
	    00h successful
	    01h failed
	BX = bytes per scan line
	CX = number of pixels per scan line
	DX = maximum number of scan lines
Notes:	if the desired width is not achievable, the next larger width will be
	  set
	the scan line may be wider than the visible area of the screen
	this function is valid in text modes, provided that pixel values are
	  multiplied by the character cell width/height
