So instead of using Garmins housenumber search you want to add a small 
road for each POI named with "${streetname} ${housenumber}'?
Technically this sounds quite easy to implement.
Some questions about that:
* Wouldn't that blow up the index size?
* Must each invisible road be connected to the rest of the road network? 
Otherwise I expect that Garmin is not able to route to the housenumbered 
streets and we get thousands of routing islands?
* mkgmap would have to modify/create a TYP file with one invisible road 
type. Should this be processed by mkgmap or is that a task of the map 
generator to ensure that the additional road type is invisible?
