I guess you could also get into the device driver. The kernel assigns the lowest possible network name available when you make the system call register_netdev(). Typically as I stated before the order in which the device driver would call this function is based upon which PCI slot they live in and which memory address is attributed with that slot. So, the initial suggestion by Tony to look at the motherboard specs would prove most useful if the memory addresses ofr the PCI interfaces are listed there. They may also be printed on the silkscreen of the Motherboard. You could also change the driver to read them in a specific order, but it all depends on how detailed and low-level you want to get. :-)
If I were a betting man though, and if your machine were AT/ATX form factor in some kind of tower, eth0 would be the further from the base of the machine.
