If you can use PostGIS, load this file:
http://www.census.gov/geo/cob/bdy/co/co00shp/co99_d00_shp.zip
and do a query to extract the bboxes for all the counties.

If you need more help, post a not to the list and I'm sure we can help 
you. If not able to use PostGIS, then use a Perl or PHP shapefile tool 
to extract the bboxes and print them to a text file.
