Yes, support for using the cdc_ncm interface in ModemManger is already available. The same goes for the older ericsson modules using the cdc_ether interface. No need for PPP anymore. You may have to add your vid/pid to the /lib/udev/rules.d/77-mm-ericsson-mbm.rules (.../plugins/77-mm-ericsson-mbm.rules if you have the MM sources checked out) file to get ModemManager to recognize it (then run "sudo udevadm control --reload-rules" and restart modemmanager).
