for two rasters you can use the d.shadedmap module for a similar effect. It's just a wrapper around a trick with the d.his module. examples: http://grass.osgeo.org/grass63/screenshots/images/fourmaps.jpg http://grass.osgeo.org/grass63/screenshots/images/spearfish_catchements.png (see raster screenshots on the homepage for scripts that made those) It's a bit limited in what it can be used for, but for the case of a categorical area map (maybe 'v.to.rast type=area') over a shaded relief DEM it works quite nicely.
