-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.
