I believe all the current ones have a framebuffer underneath them. Basically, get your hands on the porting guide, and implement SetSpans, GetSpans and FillSpans. And use mi for the rest. That should give you a functional server, albeit slow. Then you can start on the higher level functions to implement a faster Xserver.
