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.
