You may need to make changes to the 10-modem.fdi file so Network Manager
will pick it up correctly.  I had to do this with a newer EVDO usb card
from verizon.  Just do some searching on the internet.  A quick search
turned up this one:

Obviously your entries in 10-modem.fdi wont match exactly depending on
your card.

Alternatively you can just configure pptp / if scripts and connect via
the command line using ifup.
