Yes, I did not bear in mind that the city name is completely empty. 
Maybe this info is also helpful for Steve but I will also check the 
mkgmap code what's happening with elements without a city name.

The default rules use admin levels 8,7,9 and 10 for the city name. 
Please let me know if your second austrian rule with admin_level6 should 
be included in the mkgmap default style. Anyhow we will check whats 
happening if no city name is assigned.
