in gr6.5 and 7 there is a new flag -l to get around that.
"Force Lat/Lon maps to fit into geographic coordinates (90N,S; 180E,W)"

if earlier ver, use gdal_translate to convert to geotiff and

once it is inside.

usually a simple-xy location is for that, but then you have
to rectify it into a geo-location.

often r.in.gdal does this for you.
