As a followup to 71a082efc9fdc12068a3cee6cebb1330b00ebeee, it's conceivable that some vendors may expose PCI hotplug functionality through both vendor mechanisms and ACPI. The native mechanism will generally be a superset of any functionality provided via ACPI, so the acpiphp driver should always be initialised after any others. Change the link order such that acpiphp will not be initialised until any other statically linked drivers have had an opportunity to claim the hardware.
