If I were to take a wild stab on which vendor would be first to
provide a usable 8-bit implementation, it'd be ISC.  They seem to be
very dedicated to producing a good X server.

For the time being, I have some code to do image color depth reduction
which seems to work very well.  It was developed for displaying 8-bit
images on the 4-bit display of the IBM RT (it's a general algorithm)
and seems to work fairly well if you really don't need the full color
resolution.  You can get the software package, called xloadimage, from
expo.lcs.mit.edu via anonymous ftp (/contrib/xloadimage.tar.Z), or
from a recent posting in comp.sources.x.  It currently handles X
bitmap (both X10 & X11), Sun Rasterfile images, Faces Project images,
and PBM images.  GIF and XPM formats will be out soon.  Besides depth
reduction, it does a number of other image manipulations (eg zoom,
brighten, dither).  Might be useful to someone, and it certainly works
for me.

Happy hacking,
