Yes. Perhaps the answer to RTEMS is to get a single, simple
framebuffer interface defined, and have well-defined entry points
into separate chipset specific .c files elsewhere. This is what Linux
first tried to do I think, but the console code ended up being wound
into each of the chipset drivers, and now, it's huge and too complicated.
Having the chipset specific stuff in separate files, and NOT having
anything to do with the console structures would be great, since
the code could be reused for PK, or, for Microwindows in "bare
hardware" mode.
