And if it happens to be in a hotplug slot today with a suitable hotplug 
module (term?) loaded like acpiphp you can then map that to a more human 
friendly slot number/name.  In the future, once Alex Chiang's pci slots 
patches make it to mainline it will be possible even with non-hotplug slots.

netperf omni tests and a couple other tools try to find such mappings today.
