I'm not sure why Bill's dual-port card is showing up with two
interrupts, but mine doesn't.  It was my (limited) understanding that
isn't even possible on a single PCI slot. :-)

This happens to be the Compaq branded version of the Intel Dual-port
card on FreeBSD 3.4-STABLE:

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
