I can confirm this from my (limited) experience to export data
to KML. To correct for the geoid heights, you could use the previously
indicated map and calculate the local ellipsoid-geoid difference
and vertically shift your vector data with v.transform. Then export
to KML. For raster, use r.mapcalc to shift.
