I couldn't figure out how to get native queries working, so have resolved in a slightly hacky way:

$id = $em->getConnection()->fetchColumn("SELECT
    pages.id
    FROM
    pages
    INNER JOIN siteversion_page ON siteversion_page.page_id = pages.id
    INNER JOIN siteversions ON siteversion_page.siteversion_id = siteversions.id
    WHERE siteversions.id = 1
    AND pages.slug = 'index'");

$page = $em->find('Page', $id);

I don't like it because it results in more queries to the database (especially if I need to fetch an array of pages instead of one) but it works.

Edit: I've decided to just go with a class for the association. Now I can do this query:

SELECT p FROM Page p, SiteVersionPageLink l
WHERE l.page = p AND l.siteVersion = 5 AND p.slug = 'index'
