It won't hurt to switch a device on twice.  It should be ok to
do a top-level tree walk of all device objects and turn them on
before probing child devices I think.  ACPI shouldn't turn off
devices that don't probe like PCI does though because ACPI has
duplicate objects of things like the entire PCI device tree. :-/

Feel free to submit changes to the power tree btw.
