Right, ogr2osm should be one of them. I guess I will have to go back 
from osm to shape format and then try my luck with these converters.

Do you know if there is any shape file converter that would merge nearby 
nodes to a single OSM node id? In this data set, adjacent areas 
sometimes have nodes in almost the same position. This should be a 
problem in the original dataset and not a coordinate transformation 
artefact, because a transformation could map multiple points to one 
point, but not vice versa.
