Customize a "Feature"
Use the strongarm module. When creating the feature select "Strongarm" from the component section then look for the variables that start with ant_{content type name}

Automatic Nodetitle can have up to 3 different variables for every content type.

ant_'{content type name}
ant_pattern_'{content type name}
ant_php_'{content type name}

Export those variables out with your content type and you should be ok.

This works in Drupal 6 &amp; 7.
