I'm probably missing something here, but how does that help ?  The 
problem is that if that the eth0 module fails to load for whatever 
reason, then the card that would normally be eth1 would be known as eth0.

If you provide aliases... all that means is that you can do

modprobe eth0
modprobe eth1

but ... as far as I understand it, those module aliases names have no 
link to the name the kernel allocates to the interface, so if eth0 
failed, it would load eth1 (aliased to eepro100), and the eepro100 would 
be known as eth0 to the kernel.

Or is there some kludgy relationship between module alias names and 
interface names ?

I assumed there was a relationship... I can't really test that from here.. 
but um.. I assume it would load eth1 as eepro100 ?? if you compile your 
network devices into the kernel, then you may hafta get a little trickier

PS: why doesn't my mail client treat this as a list like redhat's ?
