I mis-spoke, the module I'm talking about is the cx3110x.  Too easy to
get all the module names mixed together after a while.

The problem is that while the module on the dev site works (mostly, I've
still seen weird problems coming out of monitor mode, sometimes going
in), the module in the firmware (at least, the module in Bora) still has
the old code which tends to lock up the wireless after about 30 seconds
of switching into monitor mode, as well as having a lot of problems
switching in and out of monitor mode.  This may in fact be a channel set
problem, since most drivers which work briefly and then drop dead are
usually exhibiting a channel command issue rather than an rfmon issue
(one packet is very much the same as the next in rfmon, and no real
reason it ought to care, in general).

So, at the moment, the chances of it causing weird to outright broken
behavior on a standard nokia tablet are too high for me to be
comfortable releasing an official kismet package.  While it's possible
for me to include the latest cx32110x module, it would also require
disabling the users wireless, unloading the modules, loading the new
one, running the chroot to initfs to reconfigure the wireless, and then
being absolutely sure that the process is reversed on any exit
condition, including the user closing the terminal they have kismet
running in -- otherwise they get stuck in some weird state requiring a
reboot, and that's not good behavior.

Thus is my dilemma.
