Will the MIT server be updated to report the significant bits per
pixel?

Even this is not guaranteed to get a nice result.  A HP 98788A/98548A
reports a 4 cell colormap on our modified MIT server.  This means that
"vital" programs like xconq and xcalc start using lots of colors which
all get mapped to the same shade.  I guess they should check for the
visual class as well.
