 In r23928 we added functionality to:

 * Store the post format as meta on revisions (including autosaves).
 * Add post formats data (post meta) when autosaving.

 '''There is still no way to autosave and revision custom post
 meta.'''[[BR]]
 Adding a filter to _wp_post_revision_meta_keys() will allow developers and
 plugin authors to effectively save post_meta revisions.
