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

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

  34           should say 'Y'.
