Assignment of devices must be done on kernel level (since that is a 
level on which particular interface is pronounced to be eth0 or eth1). 
If two cards use different drivers, and both are compiled as modules, 
you can do it from /etc/modprobe.conf.  Just edit the file, replace 
eth0/eth1 as you want them to be assigned, and reboot.

For example, one might have:

alias eth0 le
alias eth1 hme

To swap assignment, simply change to:

alias eth0 hme
alias eth1 le

If they are using same driver, modprobe.conf will read something like this:

alias eth0 hme
alias eht1 hme

I'm not sure how the cards that use same driver are enumerated. 
Probably first found, first serve basis.  It *should* be possible to 
specify the instance somewhere as option in modprobe.conf (for example, 
assighn eth0 to second instance, and eth1 to first instance), but I've 
no idea what is the syntax (and probably a bit lazy to look it up, since 
I don't need it right now ;-)
