My personal method is (if I understand correctly what you mean) if I dom't
know the corners in the target location:

1. go into source location, set region as I need
2. run there v.in.region to generate region box vector map

3. go into target location
4. run v.proj to reproject region box vector map from source location
5. run g.region vect=region_box res=value -pa
6. run r.proj to reproject desired raster map.

Like this I don't need cs2cs or m.proj, through the "box" trick I get the
corners easily reprojected.
(see also r.proj manual page for this hint)
