There seems to be some bad interaction between PCI VECTOR
(use_pci_vector()) and ACPI PRTs. Namely, both mp_parse_prt() and
pcibios_fixup_irqs() do the IO_APIC_VECTOR() translation on irq, the
result being IO_APIC_VECTOR(IO_APIC_VECTOR(irq)). I wonder if this is
the cause of some bug reports with acpi and pci vector? Maybe
mp_parse_prt() should not do the irq->vector translation?
