The whole point of the patch was to avoid sending any command to the secondary port, while still configuring the handlers to get unsolicited messages for signal quality and registration updates and such. But I just checked the logs again and the modem returns an error to AT+CIND=?, which means we will probably not get any CIEV unsolicited messages, and therefore we do need to periodically query for signal quality/registration status. And to do that while connected, we need to be able to send commands to the secondary port.
Hum... not really fixed.

I'll try to prepare a new patch with the ideas Dan gave in the ML: mail.gnome. org/archives/ networkmanager- list/2012- January/ msg00123. html
