From Net-HOWTO:
6.3.1. If your driver is a module (Normal with newer distros)
The module will typically can detect all of the installed cards.
Information from the detection is stored in the file:

/etc/conf.modules.

Consider that a user has 3 NE2000 cards, one at 0x300 one at 0x240, and one
at 0x220. You would add the following lines to the /etc/conf.modules
file:

        alias eth0 ne
        alias eth1 ne
        alias eth2 ne
                                                           
        options ne io=0x220,0x240,0x300

What this does is tell the program modprobe to look for 3 NE based cards at
the following addresses. It also states in which order they should be found
and the device they should be assigned.
