Did you explicitly create the overview when loading the raster using the -l OVERVIEW_FACTOR option? There is a bug right now in the driver preventing it from working with overviews: http://trac.osgeo.org/gdal/ticket/4416 You have to execute rtpostgis_legacy.sql to rename the necessary columns to the old names.
