This manual page does not yet document PAE and how it affects memory-space
mapping of PCI devices.
The kernel PCI code has a number of references to 'slot numbers'.
These do not refer to the geographic location of PCI devices,
but to the device number assigned by the combination of the PCI IDSEL
mechanism and the platform firmware.
This should be taken note of when working with the kernel PCI code.
