Yes.
use /proc/pci or /proc/bus/pci/devices
Eg. I have the devices:
Bus 0, device 10, function 0: Medium devsel. IRQ 9. I/O at 0x6400 [0x6401]. Bus 0, device 11, function 0: Medium devsel. IRQ 12. I/O at 0x6500 [0x6501].
ifconfig tells me: eth0 Link encap:Ethernet HWaddr 00:00:C0:FF:EE:00 Interrupt:9 Base address:0x6400
eth1 Link encap:Ethernet HWaddr 00:C1:49:00:DE:AD Interrupt:12 Base address:0x6500
which tells me device 10 is eth0 and device 11 is eth1 (compare I/O addresses and IRQs)
Simple enough to write a small perl (or bash) script that does the comparison.
