In case anyone is still subscribed to this thread, I just posted a new approach to stopping logging on the Kindle Touch that I believe to be safe, as well as an analysis of just what is logged.

One nice thing about this approach, in response to what abookreader wrote above, is that you can confirm that it's working by typing ;dm in the search bar, and seeing how no log messages older than 15 minutes are in the results (it stops them from being archived on the device in the first place)
