I'm having the same results. Mapper loads just fine, but looking for the internal GPS on a 810 is another story. I loaded up the internal map program, waited until I saw the GPS icon then started maemo mapper and sure enough, it found the GPS device. But thats not going to work in the real world.

I'll experiment a little more and see if I can get the loopback bluetooth thing to work. My guess is you'll have to insert some code to get the internal GPS started up.

Thanks again for the latest version, personally I still love it loads better than the one that comes with the 810

Although, when I've been unable to connect to the GPX web page I think I've cursed your name a few times ;-)
