Node.js + Express - How to get Mustache partials working?

I'm trying to get Mustache working properly with Express, and as one can guess, I'm having troubles.

The following line initializes Mustache nice and clean. Variables render as expected.

app.register('html', require(__dirname+'/public/js/libs/mustache.js'));

However, the problems start to rise when partials are thrown in the mix. With Mustache, this here partial should invoke header view/partial.

{{> header}}

But alas, nothing happens. :/ Even when I offer the partial directly, Mustache fails to render it.

app.get('/', function(req, res) {
    res.render('welcome', {
        partials: {
            header: '<h1>Header</h1>'           
        }
    });
});

So, it seems that the partials aren't working at all. I've found one hack that get's the partials somewhat working:

After that the partials render when offered directly at render call (see above), but it still fails on rendering the partials directly to views/layouts:

Layout looks something like this:

Behold, the header
{{> header}}
<p>Let's move to more important stuff...</p>

Header view looks something like this:

<h1>Header</h1>

Express can load the views by themselves just ok, but it doesn't know how to handle the Mustache partials...
