Wouldn't it make sense for the splitter - if we already have this
boundary file - to  split "tiles" primarily by political boundaries
and only if one of them contains too many nodes, devide them by a
straight line?

I think I read on this list before that in theory, polygon-shaped
tiles are no problem in garmin format.

This would make it easier for mkgmap to assign the adress information
and a meaningful "name" per tile.
