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

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

  33           communicates with the DCON using model-specific code.  If you
  34           have an XO-1.5 (or if you're unsure what model you have), you
  35           should say 'Y'.
