Just indicating that a module has been altered is too limited, IMO.

Journal module (http://drupal.org/project/journal) recently implemented a
"Patch log" feature (only available in latest dev snapshot currently), which
allows you to keep track of any patches and hacks you applied to the modules
on your site.

This means you can lookup whether you can safely update to a later version
of a module (given the possibility that your patch has been committed).
