My patches are part of various q800 branches I have been playing with over the past couple of months, and so are lagging quite far behind master. If you are able to update them based upon Peter's comments them I'm happy to review them (and perhaps could perhaps take them along with my cmd646 patchset if required). ATB, Mark.
