The geobase2osm.py script lets you pass a bounds file (with the -b option).
This will only include roads that pass through the bounds specified in the
file. So you can take the full provincial GML files but only generate .osm
files for smaller chunks.
As Jason mentions in his other post, adjoining chunks will have duplicate
ways. I don't think it will be that difficult to eliminate these
duplicates though. We just need a script that searches for two OSM ways
with the same geobase_nid that occupy the same space, and delete one of them
+ merge in any adjoining ways.
