how does -r not work? I have used -r many times without problems.
Note that it may look wrong in gv but still print correctly.
Does -r work correctly for you using A4?

Also note that the raster (or rgb) map is optional.

easy modification (in C) for a one-off job--

in ps/ps.map/ps_map.c move this down a few lines, ie after both calls to
do_vectors():

    /* do the raster stuff, if any */
    if (PS.do_raster || grp.do_group) PS_raster_plot();
