I'm working on a CIVIC driver but progress is somewhat slow since I'm having
a heck of a time trying to figure out all of the CIVIC's registers. I'm
planning on at least supporting palette control in the first intvid release
if I can. Depth/Resolution switching is another matter entirely.

However, if you want to run in 16 or 24 bit mode that's more a matter of
modifying the X server. In 16 and 24 bit mode the palette is set to a
trilinear color ramp so you essentially get a fixed mode. You could boot
into 16 or 24 bit mode and use X right now if you modify the X server to
do so.
