Yes, Mapnik supports both SQLite and Spatialite through an SQLite datasource plugin.
You can push OSM data extracts from PostGIS to SQLite using http://trac.mapnik.org/browser/trunk/utils/pgsql2sqlite and its not too hard to touch up the few parts of the osm.xml that using postgres specific syntax so that the Mapnik layer definitions (SQL queries) are compatible with SQLite.
