How to make eth0 driver permanent?

Under Fedora Core 2, the default NIC driver is e100,
and there was an entry in my /etc/modules.conf file
for it:

alias eth0 e100

I want to use the eepro100 driver, so I changed the
above line to:

alias eth0 eepro100

However, when I reboot the e100 module is still loaded:

antares:/downloads> lsmod|grep 100
e100 25092 0
mii 3584 1 e100

What do I have to do to make this permanent?

-Thanks
