Has anyone got any suggestions? My rule of thumb with Mapnik is "it's always a projection problem". Are you sure that your db is in latlong? By default osm2pgsql is in spherical mercator. If that's not it, I'd suggest starting with the generate_image.py and the osm.xml from OSM SVN, and get that working with all the defaults as described on the wiki. You can then step through changes one at a time (e.g. changing your db to latlong instead of spherical mercator, using your own style instead of osm.xml and so on.
