I used OSM_generate (http://www.cferrero.net/maps/osm_generate.html)  
to create a map consisting of a grid of POIs between 0x0001 and  
0x7fff, then laboriously right-clicked them in MapSource (v 6.15.11)  
and saw if the properties info box that popped up included a box for  
an address.  You can see the results here:

I haven't got round to repeating the exercise with my GPS unit, so I  
can't guarantee that the range is the same, though my experience  
suggests that MapSource is fairly consistent with the GPS units for  
this sort of thing (though completely inconsistent with icons used,  
for example).
