switching NICs

so i've got two NICs in this redhat/fedora machine, eth1 and eth0. i need to switch which NIC is assigned to which eth. i tried changing /etc/sysconfig/hwconf and swapping the ifcfg-ethx files in network-scripts (which have HWADDR lines) and restarting networking. no dice. now the hwconf file and the ifcfg files directly contradict the output of ip addr sh and ifconfig.

any ideas?
