There isn't a clean solution that I can find, but the best workaround seems to be something like this, using instanceof to figure out what type of data you are dealing with.

private static void bindPreferenceSummaryToValue(Preference preference) {
    // Set the listener to watch for value changes.
    preference
            .setOnPreferenceChangeListener(sBindPreferenceSummaryToValueListener);


    if (preference instanceof SeekBarPreference)
    {
        // Trigger the listener immediately with the preference's
        // current value.
        sBindPreferenceSummaryToValueListener.onPreferenceChange(
                preference,
                PreferenceManager.getDefaultSharedPreferences(
                        preference.getContext()).getInt(preference.getKey(),0));
    }
    else if (preference instanceof CheckBoxPreference)
    {
        // Trigger the listener immediately with the preference's
        // current value.
        sBindPreferenceSummaryToValueListener.onPreferenceChange(
                preference,
                PreferenceManager.getDefaultSharedPreferences(
                        preference.getContext()).getBoolean(preference.getKey(),true));
    }
}
