I assume that you have identical network cards (if you don't then just use
aliases in modules.conf to set them the way you want).
Otherwise the card with the lower PCI bus address will be eth0. Usually
the addresses go from top to bottom or bottom to top on the M/board, so if
there are other cards in the board you can check by running lspci and
comparing the addresses listed with the order of the cards on the back of
the box. For example on the box I have with 2 ethernet cards lspci gives:
00:09.0 Multimedia audio controller: Trident Microsystems 4DWave NX (rev
02)
00:0d.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8029(AS)
00:0f.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8029(AS)
01:00.0 VGA compatible controller: 3Dfx Interactive, Inc. Voodoo 3 (rev
01)
Now I know that the sound card is below the ethernet cards, therefore eth0
is the physically lower card.
