What about if you include a `route` parameter in the URL with the actual lat/lon values? I think in that case it will use those rather than rerunning the geocode? So something like:

```
OSM.router.route("/directions?" + querystring.stringify({
  from: $("#route_to").val(),
  to: $("#route_from").val(),
  route: from_lat + "," + from_lon + ";" + to_lat + "," + to_lon
}));
```

although I haven't looked at how to get hold of the lat/lon values yet.
