I once had exactly the same problem. I used the osm2pgsql-tool from OSM
to import the .osm-file to the database without the "-m" switch an
gpsdrive worked but the mapnik-scripts from OSM ("generate_image.py"),
didn't work correctly. Then I imported once again with the -m switch and
then the scripts worked but gpsdrive showed me a map about 25 km south
of my actual position. (I was at exactly 50°N and gpsdrive showed me the
map of 49.8°N).
Then I changed the projection-definition somewhere in
/usr/share/gpsdrive to match what the OSM-scripts used and since then
both work
