Just a tip that I mentioned in the Faircrack topic.
You need the power kernel from the list at page 1 in order to be able to load the injection drivers properly.
You must have kernel-power_2.6.28-maemo46-wl1
I had the kernel from extras repositories and I had errors like wlan0 device not found or insmod: invalid parameters.
You should also install the packages at page 1 manually in terminal and not by opening them with HAM.
