There was a v.in.tiger.scs program in GRASS 4.0 that extracted
the county boundary using BOU for the CFCC.  It was written by
Paul Fukuhara at our National Cartographic and GIS Center in
Ft. Worth, TX.  The NCG number is 817-334-5559 and hit 0 to get
an operator (I can't remember his extension).  Maybe Paul can
tell you if there is a 4.1 version out there. 

Good luck.  Give me a call if you need help.
