And to keep up with the "talking to myself theme"....there is a settin
under the Network Manager that purports to control mobile broadband, but it
doesn't seem to work (the device remains powered). The answer appears to be
(for *buntu on a ThinkPad):
    sudo sh -c 'echo 0 > /sys/devices/platform/thinkpad_acpi/wwan_enable'

Re-enable with:
    sudo sh -c 'echo 1 > /sys/devices/platform/thinkpad_acpi/wwan_enable'

It's a bit poor that you have to invoke the root account to do this. I
recall a certain Mr. Torvalds had some things to say about needing admin
rights to perform basic functions such as adding a printer.

Now to add that to some kind of start script and see if there is a way to
remove the need for sudo. And stop spamming the list. :-)
