We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg file should follow the pattern /pci@i0cf8,%x/... for devices that live behind an extra root bus. The extra root bus in question is the %x'th among the extra root buses. (In other words, %x gives the position of the affected extra root bus relative to the other extra root buses, in bus_nr order.) %x starts at 1, and is formatted in hex. The portion of the unit address that comes before the comma is dynamically taken from the main host bridge, similarly to sysbus_get_fw_dev_path().
