Unable to totally get rid of CONFIG_INPUT options with 2.6.6

I have a machine whose only contacts with the outside world are ethernet and serial. For some reason, it appears to be impossible to disable CONFIG_INPUT. Is this by design? I have everything removed from the input config screen, but after some digging it appears that CONFIG_INPUT is not actually controlled by any config files.

Is this an issue? Would I save anything by manually editing it out?

Thanks,
Chris

#
# Input device support
#
CONFIG_INPUT=y

#
# Userland interfaces
#
CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_MOUSEDEV_PSAUX=y
CONFIG_INPUT_MOUSEDEV_SCREEN_X=1024
CONFIG_INPUT_MOUSEDEV_SCREEN_Y=768
# CONFIG_INPUT_JOYDEV is not set
# CONFIG_INPUT_TSDEV is not set
# CONFIG_INPUT_EVDEV is not set
# CONFIG_INPUT_EVBUG is not set

Enable CONFIG_EMBEDDED, then you'll be able to get rid of INPUT_MOUSEDEV etc.
