That's because it's only a dirty hack alltogether. It would be bit 
cleaner if there was a seperate file inside the style-file where one can 
specify the poi to areas keys. Currently mkgmap can only know what kind 
of POI to create, if it also has a matching Polygon. That's as far as I 
understood the principle. Even with a seperate file it would still be a 
rather dirty hack, as it would be much better to have the POI inside 
openstretmap at first hand. I don't really think it is good style to map 
POIs for areas. Maybe a better solution would be to not create a poi, 
but just match in the search indexes (but I don't know if that is 
possible, I deem this to be impossible).
