Why? Where is the difference if I use DBus introspection or check the keys
directly? I need to do one of both (because I don't need to show the user
the option to suspend if the interface is not there) and check HAL the 
simplest way.

But they maybe want know if you could suspend in general (e.g. by echo mem
to /sys/power/state) and if you can really suspend.
