Sierra aircard 880U not recognised as a modem by hal

Despite many similar modems being included in the /usr/share/hal/fdi/information/10freedesktop/10-modem.fdi file, this one is not. This means that this modem cannot be used with network-manager

This is easily fixed by adding something similar to the following to the above file (Note that this is my fix which I created as a new file in /etc/hal/fdi/information)

<?xml version="1.0" encoding="UTF-8"?> <!-- -*- -->

<deviceinfo version="0.2">
  <device>
    <match key="info.category" string="serial">
      <!-- Sierra Wireless -->
      <match <email address hidden>:usb.vendor_id" int="0x1199">
        <!-- AirCard 880 U -->
        <match <email address hidden>:usb.product_id" int_outof="0x6855">
          <match <email address hidden>:usb.interface.number" int="0">
            <match key="serial.port" int="0">
              <append key="modem.command_sets" type="strlist">GSM-07.07</append>
              <append key="info.capabilities" type="strlist">modem</append>
            </match>
          </match>
        </match>
      </match>
    </match>
  </device>
</deviceinfo>

Pardon me if there are any obviously better ways of doing this, I've only just been finding out how this works.
