Here's how I do it:

    def translate(text, comment=''):
        """Translation function that sets context to calling module's
           filename"""
        try:
            frame = sys._getframe(1)
            fileName = frame.f_code.co_filename
        finally:
            del frame
        context = os.path.basename(os.path.splitext(fileName)[0])
        return unicode(QtCore.QCoreApplication.translate(context, text,
                                                         comment))

    def markNoTranslate(text, comment=''):
        """Mark text for translation without actually doing the
           translation"""
        return text

    __builtin__._ = translate
    __builtin__.N_ = markNoTranslate

I don't know.
