There is another problem with not supporting static ip's in network manager. VPN connections through NM depend on a network connection alread configured through NM. So if you have a static LAN which you use to connect to VPN you cannot activate them.
NM in Fedora seems to be able to parse the stuff in /etc/sysconfig/ifcfg/. Making something similar for /etc/network/interfaces would be ideal IMHO since it'll use the already used System -> Administration -> Networking configuration.
