Where? Somewhere else in sysfs? /sys/bus/pci/slots/ only gets populated when a hotplug driver or pci_slot are loaded. And if those slots aren't hotplug capable, then that directory won't get populated. Finally, if the slots aren't described by ACPI, that directory also won't get populated. If it's a relatively modern board, maybe they implement some of the new SMBIOS fields that associate PCI bus:devfn to physical slots...
