If they present a plain memory-mapped framebuffer via wscons, then you
*could* use XFree86 with the wsfb driver. Xsun is almost certainly
easier, but XFree86 has a few advantages over it, like support for
some newer X extensions (XTEST and RENDER can be kind of handy), and
the use of a shadow buffer for the framebuffer that can speed up some
operations.

(hmm, I should go try wsfb on the cg3 in my 3/80...)
