RTFM eh?

To answer my own questions: "The current implementation is not capable to connect pads to rectangles and polygons." Translation: you've got to do the thermals yourself.

Solved that by splitting my .nets file into "Power" and "Everything Else". Route Power with the regular autorouter, route Everything Else with toporouter.

The toporouter is fabulous at finding routes. It would be totally fabulous if it could do vias.
