Comment(by pgf):

 i'm seeing a (possible) variant of this behavior on my XO-1.5.  after
 running for many hours, mostly on, but also transported home in lid-close
 suspend, then plugged in and opened up, the keyboard is no longer fully
 functional.  pressing keys sometimes gives a ctrl- version of the same
 key.  mostly it gives nothing at all.  sometimes the key produces itself
 (!).

 i was prepared, and had booted initially with serial connected, so i had
 access to a serial console. in this state, an strace of kbdshim shows that
 it is seeing every keypress.

 running
 {{{
 DISPLAY=:0 xev
 }}}
 at the console showed that X11 is not seeing input events from the
 keyboard.  (the touchpad remains fully functional, throughout.)

 stopping kbdshim had no effect.  restarting kbdshim also had no effect.

 switching to a VT ("chvt 2" at the serial console) showed that the VT
 session was not getting keyboard events either.

 however: running "evtest", and selecting the uinput device (when kbdshim
 was running) or the keyboard (when kbdshim was not) showed every single
 character typed being made available, and correctly.

 i'm running os5, kernel 2.6.35.13_xo1.5-20110801.1409.olpc.66488fe .
