However, this won't work for house numbers as polygons for streets definitely make no sense - especially taking into account how weird the houses of a street are spread in many places...
Well, I'm not familiar with the Karlsruhe schema and other house numbering scheme's but I reckon the house numbers will eventually be linked to a way? Using the polygons you can lookup in which place the way is, and voila!
For Karlsruhe schema, it's not required that they're linked to a way and most of the time, they aren't. When you walk along a street, you just place nodes on the right and left side near the street and tag them with addr:housenumber. It doesn't make much sense to draw connection ways which aren't there in reality.
I did not mean to actually make a way to link the nodes to the street. A relation can also link an address to a way as does tagging ;-)
To define the according street, you usually use either a tag "addr:street" on the house node (this string can be compared with the highway's name) or you use a relation of type=associatedStreet which includes "street" and "house"s.
But I think this is not really an open point for discussion as the info is already in the OSM data, so the only missing bit is to convert it to the Garmin binary format. :)
If the addresses are OSM nodes then they can be compared against polygons as well, which was my point :D
