Dave and I have passed back a few emails about the 28M reset. It apppears BasicMicro added a three pin Power On Reset chip to the 28M, fixing a problem Dave saw on the original 24M. So the fix he was trying to put in is unnecessary, and conflicts with the POR circuit. Dave confirmed that the current software supports the additional 4 analog inputs. A 28M data sheet would be nice, but at this point it doesn't seem to add anything that we don't already know.
