In F18+, the NetworkManager package has no dependency on ModemManager,
but MM is installed via comps groups.  So either just don't install the
dialup group, or don't install ModemManager, and then you won't have MM
running.

If you don't want BT, then don't install Bluez; if Bluez isn't running,
then NM won't care about bluetooth hardware.
