I beg to differ. One of the very good points made in the talk was that
by tying the "vanilla" DNS name of the website and its .onion address
as alternate names, you can offer proof to your users that the .onion
URL they entered is indeed the website they were trying to reach.

Barring that, you have to trust on good faith that the random string
you found on Google is not bringing you to a malicious copy of your
destination which performs man-in-the-middle to steal your credentials
(and/or rewrites Bitcoin address since apparently that's a thing).

As for the original question, I think that you cannot get a DV
certificate for the .onion TLD at the moment. I assume that you could
go the FaceBook way and try your luck with Verisign or Digicert, but
it's probably going to cost you a few hundred of dollars.
Since you're at 32c3, you should get in touch with the EFF / Let's
Encrypt people to see if they have made plans for this issue.
