Nothing to worry about, it's just the structure HAL uses that
dbus-monitor doesn't understand.

Yes, disables it on hibernate, re-enables it on resume.

Does:

dbus-send --system --dest=com.gentoo.powersave \
                   --print-reply /com/gentoo/powersave \
                   com.gentoo.powersave.action.SuspendToDisk

work? What about :

/usr/sbin/hibernate

You might have to be using the latest / suspend2 for this to work.

You can also stick some "echo foo >> /tmp/debugging.txt" in that script,
to see what is happening.

Give that a go.
