So it really seems that not only Wavecom modems get a whole software
restart (including USB stack) when they get AT+CFUN=1. The thing is, is
removing the power-up command a solution for *all* Sierra modems or are
there any Sierra modems that really need the power-up command? If so,
we'll probably need to disable the power-up only for specific models,
like the one reported in the bug; or the other way around, enable it
only for only some specific models.

Wasn't that patch already applied to Ubuntu's MM? According to the logs
in https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/459052
that was written by Alexander Sack long ago, and possibly applied in
Ubuntu... (comment #7?)
