Do you support multiple resolutions, or do you just use the mode the BIOS has thrown you in? In the latter case, it's very simple to write a frame buffer device for it. Just look at drivers/video/{tga,of}fb.c (2.1.x) for an example. In the former case, things get a bit more complex, but still not that difficult.
We have support for a text console on 16 bpp packed pixels.

Once you have a frame buffer device, the XF68_FBDev X server should automagically works. The only caveat here is that we still have problems with 16 and 32 bpp; 8 bpp is fine. Once these are sorted out (a colormap problem: all colors are wrong), it will work fine.
