Retrieved jQuery plugin depends on jQuery 1.4+ so Drupal 6's jQuery fails on .first() and others

The plugin from https://github.com/harvesthq/chosen/ does stuff like this:

      container_div = $("
", {
        id: this.container_id,
        "class": "chzn-container" + (this.is_rtl ? ' chzn-rtl' : ''),
        style: 'width: ' + this.f_width + 'px;'
      });

Before jQuery 1.4 we can't pass in that object of attributes, and so the resulting html is simply "

Also all calls to .first() fail.

This causes the plugin to fail loading and the behavior to be broken.

The drush makefile will retrieve the main version but I think there must be a fork of the plugin to fix it for pre-1.4 jQuery. Even jquery_update's 1.3.2 isn't recent enough.
