Is there no suspend and hibernate anymore, or am I doing something wrong?
The methods RequestShutdown and RequestReboot are doing fine...

Thanks, but that's not a bug. This interface was removed some time ago

Is there another way to do this? - I've searched the Internet a few times, but didn't find anything...
Even these two don't work: http://live.gnome.org/GnomePowerManager/FAQ#How_do_I_query_or_do_actions_on_gnome-power-manager_from_my_shell_script.3F
