This is a pretty short list, and Apache won't start without them.

Other than those core modules you mentioned above, one of the most
distinguishing characteristics of modules is that they define config
directives that you then use.  I would recommend that you walk through
your configs and determine which module each and every directive comes
from.  To a reasonable degree of accuracy, that will give you the list
of modules that are really in use.  Naturally you'll find some
exception(s), but this will get you very close without a lot of
trial-and-error downtime.
