 1. Install 13.1.0 os15 on a XO-1.5 with ALPS.
  2. Click the icon in the frame to switch to pen tablet mode.  You will
 lose all touch functionality (but the keyboard will still work).

 The kernel message buffer shows:
 {{{
 [  301.207919] input: OLPC HGPK ALPS HGPK as
 /devices/platform/i8042/serio1/input/input7
 [  301.260614] atkbd serio0: Spurious ACK on isa0060/serio0. Some program
 might be trying access hardware directly.
 [  301.450137] psmouse serio1: Failed to enable mouse on isa0060/serio1
 }}}

 This works on XO-1 with the same OS build.  I might be able to setup
 another XO-1.5 to test this with.
