Here's what an Intel dual-port looks like in one of my servers:

chip5: <PCI to PCI bridge (vendor=1011 device=0024)> rev 0x03 on
pci1.9.0
Probing for devices on PCI bus 2:
fxp6: <Intel EtherExpress Pro 10/100B Ethernet> rev 0x05 int a irq 5
on pci2.4.0
fxp6: Ethernet address 00:08:c7:07:b2:95
fxp7: <Intel EtherExpress Pro 10/100B Ethernet> rev 0x05 int a irq 5
on pci2.5.0
fxp7: Ethernet address 00:08:c7:07:b2:96

The card just has its own PCI bridge with two 82558B controllers on
the other side.
