    I read the man pages of Xsun and X and it
    appears that the Xsun would only work in mono mode if one has cgtwo or cgfour
    devices.

The cgtwo should be a color display, although you can force it to run in
monochrome mode using the -mono switch to the server.  The cgfour runs
in a "dual screen" mode; it has both a mono and a color screen, with only
one "appearing" at a given time.  The R3 MIT server made the mono screen
the default, the R4 MIT server makes the color screen the default (although
you can give it the -mono switch to revert to the R3 behavior).

    Is that the only way to do it.

There is no option to turn the cgsix into a "monochrome" screen, sorry.
If you want a crude approximation you can try running the R4 server with
"-cc 0", which will make the default visual a StaticGray one (albeit one
with more than two colormap entries).
