It is the same image which I had originally generated with latex+dvips.
The image is single color.

As the color is not added by ghostscript (neither on the new, nor on the
old systems), it cannot be the fault of gs.
There might be a difference in the XLib function that displays the
PGM "rawbit" image: my old systems use XFree 3.x and the new system XFree 4.x.

Meanwhile I have testet the workaround
%newimage -zoom 350 -colors -1 "eqn.eps"
                    ^^^^^^^^^^
and found that it works both in the old and new environment.
I can live with this solution.

OTOH there have been a number of problems reported on this list with the 
display of EPS images on brand new Linux systems. Thus a closer investigation 
might be of interest.
