see  http://grass.osgeo.org/wiki/GRASS_FAQ#Errors

that is not so clear either*, but if you are using 6.4 probably the best
solution is to use gdal_translate to convert the adf grid into a GeoTiff
as an intermediary step, using the "-a_ullr -180 90 180 -90" option to
tell it what the bounds are. I'd avoid the simple XY solution mentioned
in the wiki if you already have hard numbers about what the bounds should
be set to.

[*] please help improve

The important thing to check is that the gdalinfo program can see the
bounds/projection settings. If GDAL can't figure out what they are there's
little chance GRASS can.

If you are using grass 6.5 or 7 you can just use the 'r.in.gdal -l' flag
to force it, then r.region to fix it.
