This should resolve these bug reports of the modem not working:
http://bugzilla.kernel.org/show_bug.cgi?id=4355
http://www.linuxquestions.org/questions/linux-newbie-8/connect-script-failed-on-ppp-go-123975/
I don't have hardware to test this, but the initial report in the kernel
bugzilla indicates that this change fixed the problem.
