How do I determine the bus/slot used with the pciinfo directive in dgap.conf?

In the test dgap.conf file below, how can I confirm the bus, slot numbers are correct for each pciinfo line? The Redhat EL4 dmesg shows the follow IRQ’s for the three C/X cards:

dgap: dgap-1.3-6, Digi International Part Number 40002347_C
dgap: For the tools package or updated drivers please visit http://www.digi.com
ACPI: PCI Interrupt 0000:0c:01.0[A] -> GSI 24 (level, low) -> IRQ 201 24
dgap: board 0: AccelePort CX (rev 3), irq 201
ACPI: PCI Interrupt 0000:0c:02.0[A] -> GSI 26 (level, low) -> IRQ 209 26
dgap: board 1: AccelePort CX (rev 3), irq 209
ACPI: PCI Interrupt 0000:14:01.0[A] -> GSI 19 (level, low) -> IRQ 193 19
dgap: board 2: AccelePort CX (rev 3), irq 193

This slot: 0000:0c:01.0, maps to the dgap.conf adatper showing: pciinfo 12 1 (no I.D. assigned).

This slot: 0000:0c:02.0, maps to the dgap.conf adapter with: pciinfo 12 2 (I.D.: caa)

This slot: 0000:14:01.0, maps to dgap.conf adapter with: pciinfo 20 1 (I.D. aaa).
