I merge spain and portugal maps from geofabrik (after sorting them) and 
produce routable maps download-able at 
http://mapas.alternativaslibre.es. I have done little test myself in 
border areas, but have not received any problem report from the people 
who download the maps (not so many till now ;-) ).
