When will the firmware for the DM42 be updated?

[brouhaha]

I'm willing to share my Free42 multiline patches if anyone wants them. They seemed to work reasonably well both on the prototype hardware, and when built for Linux.
I haven't kept up with Free42 changes since then, so it might take a bit of effort to bring them up to date.
In the more general sense, though, I think anyone sufficiently motivated would be better off working with Plus42.
