does LSPCI not even show the 3rd card?!?


each PCI device has A) a bus/card/function # (determined by the 
motherboard slot and such), and B) a vendor/device ID # (hard coded on 
the card)

a typical system...

the first field is the bus.slot.func number.  on this particular server, 
bus 00, 03, 04, and 05 are on the mainboard, while busses 01 and 2 are 
actual PCI slots, this machine actually has 3 SB Live cards plugged into 
it as its a sound processor.   bus 03 device 06 and 08 are the onboard 
broadcom ethernet controllers.

this i the same system shown in numeric form...

for an example, 14e4 is broadcom's vendor ID and 14e4:1645 is the 
broadcom bcm5701

these are what the OS actually works with, the vendor:device ID is 
matched up with the device driver database

I hope this helps.
