Just to jump in late on this discussion...

I cobbled together a driver for the Parallax 24-bit (dumb) framebuffer
a year or so ago.  I could map in the 4MB framebuffer, and my test
program could succesfully scribble to it.  XSun24, however, inverted
all of the colors in a particularly psychedlic way, and within a
minute or so would crash.  I don't claim to be the most competent
kernel programmer around, so it's possible I had a serious bug in my
driver, but my hunch is that there's some major problems
lurking inside of XSun24.

I'm not particularly competent at graphics programming, and had no
real desire to tackle an X server, so I left it at that.
