This seems to be everyone's problem, especially the slow page load time.It's strange that Google does not react.

Either way, you can do the same thing this site does:

• Create a div where you would like to put the ads. Let's give it the id adsense_container. For example:
  <div id=adsense_container style="display:inline;"></div>
• On the bottom of the page create an initially hidden div which contains nothing but your adsense script. For example give the id "adsense_div" to your div:
  <div id=adsense_div style=display:none>
    <script type="text/javascript"><!--
      google_ad_client = "pub-xxxxxxxxxxxxxxxx";
      google_ad_slot = "xxxxxxxxxx";
      google_ad_width = xxx;
      google_ad_height = xxx;
    //-->
    </script>
    <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>
  </div>
• Finally at the end of the page reparent the adsense_div to be inside the adsense_container:
  <script language=javascript>
      document.getElementById("adsense_container").appendChild(document.getElementById("adsense_div"));
      document.getElementById("adsense_div").style.display="inline";
  </script>
  

Hope this helps everyone.
