 > By booting a kernel without mmp-camera module(CONFIG_VIDEO_MMP_CAMERA),
 I no longer get "''psmouse.c: Failed to enable mouse on
 olpc_touchpad/serio''" message anymore.

 thank you for this report.   i have a pending firmware change which will
 definitely help with this issue, but i'm at a loss as to how the camera
 might affect it.  i'll investigate that.

 fyi, a much faster way to reproduce the problem, without rebooting, is:

 {{{
 modprobe -r psmouse; modprobe psmouse
 }}}

 this is known to fail completely after the laptop has suspended and
 resumed at least once, so it's a more interesting test before the first
 suspend.
