At the moment, NM can't do this; it's an old bug and NM should allow
both a local address and the PPPoE address but that must be fixed.

In the mean time, you could create a NetworkManager dispatcher script
that adds the static IP address by running something like "ifconfig em1
192.168.1.254/24" to em1 whenever the PPP connection is brought up;
check out 'man NetworkManager' and the dispatcher examples here:
