---------------------------------+------------------------------------------
 On an XO-1.5 B2, B3, or C1 prototype, running a firmware earlier than
 Q3A26, the lid switch is unreliable.  It may always report that the lid is
 closed, depending on the phase of the moon.

 This was a miscommunication between the schematics and the EC firmware.
 In earlier versions of EC firmware GPIO 0C, which is wired to the
 LID_SWITCH signal along with the southbridge, is always driven low when
 the laptop is powered.
