    Sorry to join this discussion so late.

    ACPI tells us the resources used by devices. Today, we don't reserve
    ACPI resources until a driver claims a device. PCI does some sort of
    reservation up front, before the driver claims devices. Conceptually,
    I think ACPI should do the same thing, and I don't think it's that
    hard to do.

    But breaking things like lmsensors would make the transition painful.
