There are a lot of ways to shuffle the DOM around between breakpoints.
I've used this javascript library to move blocks of markup between viewport
sizes before:
http://wicky.nillia.ms/enquire.js/

It adds media query support to JS, letting you call custom functions on and
off whatever viewport rules suite your need.  Works great in scenarios just
like this one.

Basic usage is simple like...

// Move PageNav and PageContent
Brand.OrderNavContent = function(selector1, selector2) {
  return jQ(selector1).after(jQ(selector2));
}

jQ(document).ready(function() {

  // JS Media Queries
  enquire

    // Large
    .register("screen and (min-width: 1200px)", {
      match : function() {
        Brand.OrderNavContent('div#page-nav', 'div#page-content');

    // Small
    .register("screen and (min-width: 768px) and (max-width:991px)", {
      match : function() {
        Brand.OrderNavContent('div#page-content', 'div#page-nav');

.....

Cheers,
