That's an interesting idea.  I was going to suggest just deleting all 
network interfaces and devices in system-config-network and recreating 
them, letting the configurator detect and assign the devices by type.

If you've really screwed up the configuration, you may want to do the 
redetection anyway whether you force the load order or not.
