As for unlocking all 14 channels in full power (iw reg set JP), You only need package iw-tools installed (You probably have it already, if You use any thing related to aircrack-ng), and execution of such command every time after loading stock drivers (again, it's not needed for bleeding-edge drivers, aka lxp's ones).

Here is example for advanced interface switcher - modified file /usr/bin/advifsw_wlan_on.sh
[code]#!/bin/sh
modprobe wl12xx
wl1251-cal
stop wlancond
start wlancond
ifconfig wlan0 up
sleep 1
iw reg set JP
sleep 1[/b]

So, as You can see, it consist only of adding command between two sleeps (required, to allow drivers to settle down, otherwise command may not be executed properly under some circumstances). To have full automation, You need to edit - in the same manner - every script, that is part of any program messing with loading/unloading drivers.

To find location of such files, You can use dpkg -L <packagename> (it list location of files, placed during installation of provided package), or ask in program's thread on TMO.

As for boosting power to 30 via custom kernel (module), I'm perfectly sure that it's only theoretical thing - driver's firmware also limit it for sure, and 1000 mW (1W!) is insanely impossible, unless someone want to fry egg on WLAN chip.

Ho ever if it's possible to boost it by reasonable amount and if it would be feasible (I'm pretty sure, that too high power would create noise, maybe so much, that it would outweigh benefits of boosting), is to be determine by more knowledgeable ones than me.

Maybe "little" boost - for example, 150 mW - could work well? It would be interesting, especially in tandem with external high-gain antenna, connected via hirose connector on our PCB.
