Making the Logo an Active link in Twenty Ten

I’ve been searching for a way to make the logo an active link in Twenty Ten. I’ve dropped in a background image into the site-title, but it doesn’t work. I’ve tried adding the logo manually to the header.php file. It doesn’t work. The only time I can get the active link to work is by having the text on top of the logo, which of course looks like crap. I’m working with a child theme, not modifying twenty ten directly. Any viable suggestion is welcome. I know there’s another thread for this, and someone said the issue was “resolved” though based on all the postings I’d say that’s wrong.

Thanks for any help.
