Post-import, I run a couple of queries along the lines of
UPDATE planet_osm_point SET urban=true FROM built_up_areas WHERE
using a pre-existing 'built_up_areas' table which contains polygons of,

doubt construct them from OSM landuse if that floats your boat.
The Mapnik stylesheet queries then simply respond to that column:
