    OK, so ownership is changed to ACPI.

    It's fine APL does not have PADCFG2.

    Hmm, I don't understand how this can work in Windows either. The Windows
    people told me that they don't save and restore anything else than
    padcfg registers + ie. If the ownership is changed to ACPI it means you
    don't get interrupts anymore (only GPEs) and that applies to Windows as
    well.
