How to access the node-orm2 Express middleware inside passport.deserializeUser

Question

I'm using Passport for authentication in conjunction with node-orm2. Passport requires you to register functions for serializing and deserializing users to and from the session. My users are stored in a database which I'm accessing through node-orm2's Express middleware. The orm2 middleware tags its models onto the req object for easy access. Unfortunately, Passport does not provide access to the req object in deserializeUser. I've come across this solution, but am hoping for something better:

var User;

passport.use({ passReqToCallback: true }, new LocalStrategy(function (request, username, password, done) {
    if (!User) {
        User = request.models.User;
    }

User
    .find({ username: username })
    .limit(1)
    .run(function (err, users) {
        var user = users[0];

        if (err) {
            done(err);
        } else if (!hasher.verify(password, user.password)) {
            done(null, false);
        } else {
            done(null, user);
        }
    });
}));

passport.deserializeUser(function (id, done) {
    User.get(id, done);
});

req will be passed to passport's serialize and deserialize callbacks in the upcoming release, 0.2.0: https://github.com/jaredhanson/passport/pull/160
