According to everything listed at the NAACP websites, he hasn't donated anything yet. That's not to say he hasn't, however. Many actors, after pulling something like that, will not publicize that they're donating to the same cause that they knocked (in some form or another). They do this, because it will give them more bad publicity, as surely the nay-sayers will say he's only donating out of guilt. I'm guessing if he did donate, it's well buried somewhere.
