The result of the discussion upstream is that the power-up command should only be sent to Sierra Wireless modems if not already in full functionality mode. Basically: if AT+CFUN? already replies AT+CFUN: 1, then skip the power-up command.

Implemented this already in the 'power-up-check-needed' branch in the following git repo:
 git://gitorious.org/lanedo/modemmanager.git

Already tested it with Wavecom modems, which are also affected by the issue.

Tests with Sierra Wireless models are highly appreciated.
