Finally, I've added a power-waste mode to keep the device display turned on. D-Pad up activates this, and displays a red battery icon to warn you of the consequences... Unfortunately, this function might or might not work on your device: I had BIG problems with the osso.context and the D-BUS, and it doesn't work on my device right now - however, it SHOULD :-) Glad for any feedback/fix from a more advanced developer!
