 The button configuration in drivers/input/mouse/olpc.c is quite sensitive
 and, in some configurations, causes the kernel to report "twinned clicks",
 i.e. click events from both the Pen Tablet (PT) and the Glide Sensor (GS)
 when the physical mouse buttons are pressed.

 To date, this problem has stymied efforts to revive the use of the Pen
 Tablet on the XO. Recently, Blaketh overcame this difficulty by disabling
 the ability of the Glide Sensor to send click events while preserving this
 ability on the Pen Tablet. This (combined with several other changes)
 allow us to consider reviving the use of the Pen Tablet alongside the
 Glide Sensor.

 This bug is a public record of our (presently limited) knowledge about the
 root causes of this behavior and our resulting work-arounds.
