Trying to get GOBI modem [back] to working

[Adam Tauno Williams <awilliam whitemice org>]

openSUSE 12.2 i686
NetworkManager-0.9.4.0-5.13.1.i586
ModemManager-0.5.2.0-2.4.1.i586
3.4.11-2.16-desktop #1 SMP PREEMPT

I have an HP Netbook Pavilion dm1.
Device is 03f0:241d Hewlett-Packard Gobi 2000 Wireless

It worked on a previous install, at least at some point.  Now the device
does not appear to be available [we appear to have at least the same
version of ModemManager - I do have
a /usr/lib/ModemManager/libmm-plugin-gobi.so].

Does NetworkManager / ModemManager initialize this device or does that
still fall to the gobi_loader?

Previously in /var/log/message we'd see -

The device configured as wwan0 "HP un2420 Mobile Broadband Module".

Now these additional devices do not appear [assuming the firmware is not
initialized].
