 According to various fail log I've seen, olpc-keyboard usually fails to
 get reply when mmp-camera module chimes in:

 {{{

   I've tried to do overnight rebooting test(total 1320 reboots till now)
 without mmp-camera and libertas_sdio enabled and it appears to me that
 there's no PS/2-command-issued-without-reply anymore.  Perhaps this will
 help on the FSP losing control problem observed by greenfeld?
