Just tested and amazingly it does work, just took one small code change (will be included from the next update onwards in releases). TMS however doesn't work - you need to do the manual template edits.
Replace line 364 of library/Dark/PostRating/Model.php with:
Code:
if ((!method_exists($userModel, 'isUserIgnored') || !$userModel->isUserIgnored($postUser, $user_id))
Edit: The admin interface for editing ratings with spritesheets is a little
messy, but not unusably broken
