[Bug 461524] [NEW] Powerdevil brightness OSD does not display if laptop_panel.brightness_in_hardware = true

[Zorael]

Public bug reported:

Binary package hint: kdebase-workspace

If the hal property laptop_panel.brightness_in_hardware is set to true,
Powerdevil doesn't display the brightness OSD when changing it via
brightness keys or via the panel applet. This was introduced in
4:4.3.2-0ubuntu7, whose changelog follows;

    kdebase-workspace (4:4.3.2-0ubuntu7) karmic; urgency=low

      * Update kubuntu_101_brightness_fn_keys_and_osd.diff to use the same OSD as
        kmix (LP: #458963):
        - Reverts the addition of an untranslated string
        - Reduces U/I impact of this late change
        - Updated patch thanks to Felix Geyer

    kdebase-workspace (4:4.3.2-0ubuntu6) karmic; urgency=low

      * Add kubuntu_101_brightness_fn_keys_and_osd.diff to enable brightness
        Fn keys when they aren't handled by the hardware and add an OSD
        for brightness changes

The kubuntu_101_brightness_fn_keys_and_osd.diff patch added in
4:4.3.2-0ubuntu6 fixed brightness behavior overall on this machine, as
it required Powerdevil to be aware of
laptop_panel.brightness_in_hardware to not cause strange behavior upon
changing brightness (see https://www.launchpad.net/bugs/458963).

When forcing said hal property to false (in fdi files), the OSD shows,
but then the weird brightness behavior obviously returns.
