Info about Karmic modem manager and mode switching?

this is a good start.
I have already made an own udev rule file for selected modems requiring
eject or usb_modeswitch and with it I already get the modems nicely to
modem mode. Even though, that is not enough because network manager: a)
does not recognize these modems at all or b) sees the modem but
connecting to the net miserably fails.
In addition, if the modem-modeswitch could do the same as usb_modeswitch
I would like to learn to use that instead, as it is readily there in
Ubuntu. Seems that there is only one type "option-zerocd" available. Is
it possible to add different types (like in usb_modeswitch) here?
