+       ---help---
+         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

+         Enable support for the DCON in XO-1.5 model laptops.  The kernel
