	  In order to support very low power operation, the XO laptop uses a
	  secondary Display CONtroller, or DCON.  This secondary controller
	  is present in the video pipeline between the primary display
	  controller (integrate into the processor or chipset) and the LCD
	  panel.  It allows the main processor/display controller to be
	  completely powered off while still retaining an image on the display.
	  This controller is only available on OLPC platforms.  Unless you have
	  one of these platforms, you will want to say 'N'.

	  Enable support for the DCON in XO-1 model laptops.  The kernel
	  communicates with the DCON using model-specific code.  If you
	  have an XO-1 (or if you're unsure what model you have), you should
	  say 'Y'.

	  Enable support for the DCON in XO-1.5 model laptops.  The kernel
	  communicates with the DCON using model-specific code.  If you
	  have an XO-1.5 (or if you're unsure what model you have), you
	  should say 'Y'.
