I've written a small app in c that will generate an arbitrarily large 
grid of POIs or polygons, each with a unique tag=key combination, and 
the associated mkgmap style file to go with it.  This lets you see how 
garmin type codes associate to icons and categories on any given GPS unit.

Happy to share this, or the output of it (an IMG file and associated 
style file).
