I'll pick it up from here - though may be a few days before I get to it (on wrong computer at the moment). I've not looked at the whole driver for a while. The easiest way to get feedback in general might be to do a series making the move (with move detection disabled so we see the whole code). That gives an opportunity for everyone to take a detailed look at the driver on list and comment on it in a coherent way. This is how I tend to do a review for a move out of staging anyway as it is the same treatment as a new driver gets and we should be consistent across the two.
