Yes, we did get this going.

We ended up editing the web.xml file for OpenSSO, and added an error-page
    <error-page>
        <error-code>401</error-code>
        <location>/errors/401.jsp</location>
    </error-page>

In the 401.jsp there's a response.addHeader("Www-Authenticate", "Negotiate"); and the HTML with javascript the user-agent uses to select a different module.
