It happens that I just tried this with a student yesterday. It seems  
that the new version 4 SRTM's from CGIAR do not have projection  
information in the header. (Probably need to contact someone there  
about this).

Anyway, the way to deal with this is to create a latlong region with a  
WGS84 datum and use r.in.gdal to import the SRTM. IMPORTANT: you'll  
need to set the projection override flag.

They should import fine in this way.
