(easily) without having to go to other drivers to change the magical return values. This wouldn't be so bad if there were proper defines for these constants. In particular dev/acpica/acpi_pcib_pci.c returns -1000 as the probe priority and it's expected that this driver gets to attach over the common PCI bus drivers.
