You're repeating yourself over and over, but you're missing the point.

The ACPI table does not provide a sequence, it provides a collection and
it's nowhere written in stone that this collection has to be processed
in order.

If you want a sequence then put dependencies into the table and be done
with it, no?

Thanks,
