They're managed by the NGI, and you can get the data here: 
http://www.ngi.be/gdoc/viewer.htm (you need to select a type at the bottom 
right to see the points on the map)

But I guess we're not allowed to get our information from there and put it in 
OSM. At the very least, they can claim database right on it...
