Andy (DeuceEFI) can ship you a USBDM (open sauce/sores/source) for $32 US + shipping, if you need one:

That can also let you upgrade your serial monitor on your MS2 stuff to a proper one usable by other tools. I'll attach that S19 to this post for future reference.
In terms of FreeEMS as it is, no boards are really required, and supporting board developers is just a drain on the limited resources. However, for adding this CPU to the option list, I'd need a dev board that I an access pins on, and load code to through USB.
Thanks Metaworld82, it's been a long hard road, and it's far from over yet, but the payoffs are starting to roll in
