sure - shut off NetworkManager and turn on network

chkconfig NetworkManager off
chkconfig NetworkManagerDispatcher off
chkconfig network on
service NetworkManager stop
service network restart

at this point, system-config-network will work just like it always has.

NetworkManager is useful when you are using wireless or just dhcp but
'network' service works fine with dhcp too.
