This avoids messages like this after suspend:

   cdc_ncm 2-1.4:1.6: no reset_resume for driver cdc_ncm?
   cdc_ncm 2-1.4:1.7: no reset_resume for driver cdc_ncm?
   cdc_ncm 2-1.4:1.6: usb0: unregister 'cdc_ncm' usb-0000:00:1d.0-1.4, CDC NCM

This is important for the Ericsson F5521gw GSM/UMTS modem.
Otherwise modemmanager looses the fact that the cdc_ncm and cdc_acm devices
belong together.

The cdc_ether module does the same.

Yes, it does. Have you tested this with active connections and unconnected?

Yes, I've just tested suspend while having an active connection
(My original tests where without an active connection).

BTW: I'm testing this on top of linux-image-2.6.38-8-generic from ubuntu
11.04.
