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
that was written by Alexander Sack long ago, and possibly applied in
Ubuntu... (comment #7?)
