I installed geonames_cck, geonames, geomap. Activated all the modules that the docs said I needed to but no googlemap appeared. A dev_load of the node showed that the Lat and Long parts of the field were missing. The geonames server was responding to a query so I added Latitude and Longditude to the DB manually and the map appeared :)

After activating Geoapi Iplocator Maxmind everything works fine - maybe add a dependency in the module info? or document in the README

best
