PCI cards and devices are identified with a leading 0, AGP cards with a 1. In my case I have a Matrox Millenium II (0:12:0) and a Diamond FireGL(1:0:0). Find your video cards and write down the numbers associated with them. It is important that you know which number goes with which card.
+!Alternate Method to Scanning the PCI Bus
+
+You can also find these numbers without having to shut your X server down as long as you have /proc enabled. Simply look at the contents of /proc/pci which will have the appropriate information. The three numbers you are looking for are the Bus, Device, and Function. For example, The last few lines of my /proc/pci read:
+
+----
+ Bus 0, device 9, function 0:
+ VGA compatible controller: S3 Inc. 86c764/765 Trio32/64/64V+ (rev 68).
+ IRQ 11.
+ Non-prefetchable 32 bit memory at 0xe8000000 0xebffffff.
+ Bus 1, device 5, function 0:
+ VGA compatible controller: nVidia Corporation NV10 Geforce 256 SDR (rev 16
+).
+ IRQ 11.
+ Master Capable. Latency=64. Min Gnt=5.Max Lat=1.
+ Non-prefetchable 32 bit memory at 0xe6000000 0xe6ffffff.
+ Prefetchable 32 bit memory at 0xc8000000 0xcfffffff.
+----
+As you can see, my S3 card is on Bus 0, device 9 and function 0 which would correspond to (0:9:0) from a XFree86 -scanpci output. My Geforce card would be listed as (1:5:0)
