The current Power Manager KCM is quite strange:
It doesn't really looks like it's doing anything, but forwarding all of the work to PowerDevil plugins. The PowerDevil plugins don't actually look like they are doing anything besides filling up the UI with custom Widgets inside of the plugins they appear to just store data on the configuration file, but I failed to see any kind of communication to the PowerDevil daemon. I assume it monitors the configuration file for changes.
This patch ignores looking into the PowerDevil actions, and touches the files manually (as done inside of the PowerDevil plugins)
