I just tested X11R6 with WSCONS and it works well. It's nice to see X in color and moving swiftly, although I appreciate the effort with the monochrome in R7.

The header file is pretty well documented, but I am afraid I don't have the skills to design and code the driver. I can contribute with beer-donation and testing.

It doesn't look like any of them have planar graphics mode, that I understand makes things more difficult on the Amiga.
