OZ has apmd running in order to provide suspend/resume script
functionality. In order to work around the fact that the Z will not
wake up if it gets suspended by one app while another has the device
accessed, we send a signal to apmd which results it apmd doing the
suspend. Hackish, but allows an 'apm' wrapper script to either send the
signal or call the original apm binary, depending on whether apmd is
running. apm -s always works.
