Sounds like fun :]

I just cheated and combine your TIGER roads with landmark polygons
from esri (very naughty I know) :
http://artem.dev.openstreetmap.org/files/tiger_osm.png

Dark blue and light green polygons from landmarks.

I get these CFCC codes :

planet_osm=# select distinct cfcc from tiger_landmarks; cfcc

I won't be able to look into all these till next week but It think it
would be nice to get those polygons into OSM, somehow... Ruby or C++
???

BTW, have you tried Python? I found it complements c++ nicely.
