Miguel,

I just went through this a few weeks ago myself.  If you want to check
the archives, I believe the subject was something like "nic order,
again"

As I recall my solution was to comment out the modprobe alias created
for the network cards (/etc/modprobe.conf) and then in
network-scripts, use the HWADDR in each config script.  Make sure the
device=ethX matches the name of the file, if nothing else, for your
own sanity - since the OS checks that line, and does not care what the
file is named.

Good luck!
Gordon
