Maybe you need to set the resolution to match that of the satellite image?
Beware if you have a very large map and the image is high resolution, of course.

Try r.in.onearth from the GRASS Wiki AddOns webpage, or r.in.wms
(supplied with GRASS 6.2+).

d.his + r.shaded.relief; or NVIZ with image map as the DEM's "color"
setting.
