You don't say what release of X you are running.  The MIT R4 Sun server
has an option -mono which either makes the monochrome screen the
default or eliminates the color screen entirely, I forget which.  You
could also use -dev /dev/bwtwo0 (or bwtwo1, I forget which is overlay
and which is overlay enable).

I would also say it's time to call the field circus...er, service types.

[%] Not to be snarky; it's just that I keep seeing this error and it
    eventually grated enough to provoke a response.  As the R4
    mit/README-R4 file says,

			 It's a window system named X,
			  not a system named X Window.
