Yes.

I wouldn't try to repair the damage at this point.  I'd do this:

(1) Install the initscripts update.  This will fix the random swapping of 
NIC device names.  None of the other suggestions work reliably.

(2) In system-config-network, delete all hardware devices and associated 
interfaces.  If you DHCP, clean out /var/lib/dhclient.

(3) Reboot.  This will allow initscripts to detect the NICs the way it 
wants.

(4) Recreate the interfaces in system-config-network (if necessary).
