Google Analytics: Adding search engines in the new version

As Google Analytics unlocked a few new features, they also made the new ga.js the default. I'm working on upgrading my Google Analytics for WordPress plugin to work with the new version, but I though I'd let you guys know some of the things I ran into. The first one is that adding search engines now has a different, and in my opinion much more readable, code:

pageTracker._addOrganic("name_of_searchengine","q_var");

I've got a new version of the custom_se.js for those who want it, you can download it here, and you can find the official documentation here.
