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.

Ie, not very well.
