        You may use r.info to obtain the coordinates of the opposite
        corners of the grid of the raster map.  Alternatively, you could
        change the current region to the one of the raster map ($
        g.region rast=MAP), then print it ($ g.region -p.)  (You're to
        save the current region to a temporary file to be able to return
        to it.)

        The above gives you the coordinates of the corners of the grid.
        I know no easy way to obtain the coordinates of the corners of
        the actual data (i. e., with the NULLs omitted.)
