Impact: Certain models of 3G hardware (Gobi) which apparently are quite
common, require several changes to work. First, the kernel module needs
to be updated, which requires larger modifications. Second, a new firm-
ware loader is required together with a matching udev rule.
Fix: In order to prevent regressions, the driver backport was done in
LBM and also adds a new binary subpackage (lbm-wwan). This package also
contains the loader and the udev rule.
NOTE! The drivers also requires firmware files which need to be manually
gathered as they are not redistributable.
Testcase: Without this backport no 3G connections are possible. Sevral
users in the bug report had successfully used the driver from the test
package after collecting the required firmware files.
The kernel parts are already in Maverick. But the firmware loader and the
udev rule would need to get packaged somewhere. I am not sure this still
can be done in time, so maybe the userspace part would need to go into
Maverick's LBM. Though it sounds a bit unclean.
For future releases it would be valuable to evaluate whether the firmware
might be acquired semi-automatically via fw-cutter.
