Please add modemmanager USE to 0.9.2.0-r*.ebuild, it's trivial. Upgrading to networkmanager-0.9.4.0-r2 is not possible for me until bug 410661 is fixed. Please also backport other changes from 0.9.4.0-r2 P.S. May be it is time to create networkmanager herd?
0.9.4.0-r6 is already stable and 0.9.2.x dropped
