Actually I'd encourage you to use the latest MM 0.4 beta release, which
has the following improvements that will be relevant to you:

1) doesn't expose modem on D-Bus until *all* ports have finished
probing; your traces show that NM starts to enable the device before MM
has really finished initializing it

2) prints a timestamp for debug output allowing me to easily see delays
without having to ask you

then lets do the same thing and see if we still get the problem, and if
so, what we can do about it.
