Sorry, but ive not backed up this file, instead of this, i will copy
the entire function (in fact its very short)

cpi_pcib_pci_attach(device_t dev)
{
    struct acpi_pcib_softc *sc;
    ACPI_FUNCTION_TRACE((char *)(uintptr_t)__func__);

    if (device_get_unit(dev)==2){
        pci_write_config(dev, PCIR_COMMAND, PCIM_CMD_MEMEN |
PCIM_CMD_PORTEN, 1);
        pci_enable_busmaster(dev);
        pci_write_config(dev, PCIR_IOBASEL_1, 0xf0, 1);
        pci_write_config(dev, PCIR_MEMBASE_1, 0xf020, 2);
        pci_write_config(dev, PCIR_MEMLIMIT_1, 0xf020, 2);
        pci_write_config(dev, PCIR_PMBASEL_1, 0xfff1, 2);
    }
    if (device_get_unit(dev)==3){
        pci_write_config(dev, PCIR_COMMAND, PCIM_CMD_MEMEN |
PCIM_CMD_PORTEN, 1);
        pci_enable_busmaster(dev);
        pci_write_config(dev, PCIR_IOBASEL_1, 0xf0, 1);
        pci_write_config(dev, PCIR_MEMBASE_1, 0xf030, 2);
        pci_write_config(dev, PCIR_MEMLIMIT_1, 0xf030, 2);
        pci_write_config(dev, PCIR_PMBASEL_1, 0xfff1, 2);
    }

    pcib_attach_common(dev);
    sc = device_get_softc(dev);
    sc->ap_handle = acpi_get_handle(dev);
  return (acpi_pcib_attach(dev, &sc->ap_prt, sc->ap_pcibsc.secbus));
}
