Thanks. that fixed the main OSM map. Still have:
- "2 batteries found" stderr, and "battery: -1%" on screen.
- lots of dbus errors, e.g. when I click a button and click ignored.
- tries to fetch from c.andy.sandbox.cloudmade.com and tah.openstreetmap.org which are down, but no useful error message for user.
- change map: map icons sometimes loading very slowly.

Having played with it, it does not appear to do what I needed. Will need to keep Android and N900 around for mapping, by the looks of it.
