In that case, I can suggest that you implement a local NM hook.

When a network is brought up, or down, NM will execute scripts placed
in /etc/NetworkManager/dispatcher.d/ with parameters indicating device
and up/down.

A snippet of shell that adds/removes a powerd "inhibit" file 3g
connections are established/torn down will DTRT.

You can add this trivially locally, and if it's done nice and clean we
can include it in our next OS release :-)
