Other than 386 Minix I think the biggest problem will be fitting it into
64k+64K. I dont know an implementation of X that runs this small.

As for the 68K machines or Bruces 386 version. I think kernel support for
graphics would be needed. ST Minix 1.1 once had a /dev/screen device which
gave access to the video memory which is probably all thats needed for 
graphics in that environment but PC's have a whole plethora of video cards
all of which need access to I/O ports as well. I think a kernel graphics
process would be in order. Not that I would know mind you !

I wish you luck in your endeavours
