Incase anyone is interested, turns out Ovi Maps on the N9 is qml with a few plugins for extra functions. I've been trying to get it working on my N900, but i keep hitting walls with missing libraries and others (some N9 libraries worked when I copied them over, others said it was the wrong version or file length). Alot of the plugins are available online it seems at http://gitorious.org/ so there might be a chance it can eventually work on the N900, but I'm not too hopeful

If anyone is good at qml, it would be awesome if you could get it to work
