Have you tried first displaying the raster map, then creating
a new frame with the "d.frame" command, and then displaying
the legend in this new frame with the "d.legend" command? 

You do not need a mouse to create a new frame if you run 
"d.frame" non-interactively and specify the screen coordinates
for the new frame.  The "d.legend" command prints the legend 
of a raster map in the active frame, so you need to make sure 
that you use the -cs flags when running "d.frame" to both 
create and activate the new frame.  The legend that is created 
with "d.legend" isn't particularly beautiful.  You can get 
fancier if you create a legend with "p.map" instructions, but 
this involves a lot more work.
