We're importing a small number of streets from a project called UMP
pcPL that has similar housenumber data as you describe (for *some*
streets).  Here's how my script converts it to OSM:

We add a addr:interpolation on each side of the way with an arbitrary
offset and with some simple heuristics to make it look correct
(although obviously it needs a manual check like all imported data -
to see that it corresponds with reality).  I didn't add any address
relations but addr:street value can be used to add relations
automatically if needed.  Here's a sample:
http://www.openstreetmap.org/?lat=52.23954&lon=21.10434&zoom=17&layers=B000FTF

The converter script is at http://repo.or.cz/w/ump2osm.git and the
function add_addrinfo does the projection, adds the offset, and does
the inverse projection.
