"Recent Changes" - published nodes only?

I'm trying to get the Recent Changes module to show unpublished node content revisions using drupal6.3, unsuccessfully.

The usage is as follows:
- An authenticated-user submits a story, which is automatically unpublished
- An editorial team revises the story (I'm using diff for revision tracking)

However, recent changes only shows published nodes as far as I can tell.

Does anyone else experience this problem?
