I'm not sure, but this sounds like you would like to add some routing 
capability to gpsdrive?
This would sound great :-)

I would prefer to add this as a lib directly into gpsdrive. What do you think 
about this?

You can have a look into osmtrackfilter.pl there I started reading the mapnik 
data within a perl script. Only thing missing (as what I remember) is the 
projection of the Data.

Have a look into the mapnik and poi stuff.

If pgroute is written in C/C++ and uses the postgis database of osm this would 
be one of my prefered routing implementations for GPSDrive.

I hope it will not be too much overhead.

Sounds like a good start to me.

Please keep us posted ...
