The enabling part is finished[1]. I didn't packaged the app yet, because it is almost useless since you can use only letters in the majority of the BT keyboards. I contacted the responsible for that area in order to know more about the reasons for the removal of the generic keyboards, but didn't get any reply so far . I can try to dig more about this but can be a great waste of time if they removed it for a reason [1] - https://garage.maemo.org/projects/btkeyboard/
