Thread:Extension talk:Maps/Google Earth/reply

The only layers Maps will accept are the traffic and bicycling layers you mentioned. It's possible that the Google Maps API supports additional layers, but you won't be able to use them unless support for those is added to Maps. Can you link the relevant example? If it's simple enough I might add it, if it's more complex it's up to someone else, as I can't properly test the Google Earth functionality since it lacks Linux support.
