Antoine / Hamish,

If you use gdalinfo on the dataset you should get the WKT string defining
the coordinate system, including the ellipsoid.  If you import using r.in.gdal
in the normal manner that creates a new study area with the coordinate system
defined from the source data, that should capture the definition properly.

Please let me know if you have problems with ISIS cubes through GDAL.  I'd
like to make sure the support for them is solid.

Best regards,
