Fact, at least for the 5.03 version which was the one we reverse-engineered to find this detection method.

Yes it would, but I don't know if or how that can be done.

The exact controller model is still unconfirmed. The command sequences match, but those are fairly standard across many brands of lcd controllers so that is not a safe indication.

Since the LCD is custom made for archos, the char rom in the datasheet matches neither new nor old but as you probably know we use the same code for both (with the exception of a couple of command values that differ). Also, since the LCD is a chip-on-glass design, there are no chip markings to be found anywhere.
