Yup. The Itsy port does exactly that, but one would need to make sure that whatever input devices are used can be integrated as well. X does more than just the display, it provides the input. When I wrote the Itsy code I had access to the guys that made it which helped enormously since I could get them to change the libraries to be helpful.

In principle it is easy; open /dev/fb, do whatever ioctl junk is needed, open /dev/mouse (or touchscreen or whatever) and set it up and there y'go. There are important details however, like handling the pixel endianness & RGB layout right. With extra trickery one can also save memory by making the screen buffer memory actually be part of the Display form bitmap - like I do on the Acorn port.
