Hi Nils,

I am not sure but I think your osmosis call is not 100% correct. I keeps 
only relations tagged with boundary=administrative and the ways tagged 
with boundary=administrative. If a relation contains a way not tagged 
with boundary=administrative it is thrown away. Please have a look at 
http://wiki.openstreetmap.org/wiki/Mkgmap/help/options#Using_precompiled_bounds_for_the_address_index 
where the correct osmosis call is documented (you can omit the 
postal_code things).

Looks good to me.

If the relation is tagged only the tags on the relation are used.

You can create a tag listing of all boundaries contained in the 
precompiled bounds:
java -jar mkgmap.jar 
uk.me.parabola.mkgmap.reader.osm.boundary.BoundaryLister <boundsdir>
