Incidentally, a typical piece of alternative content should usually use:
Right, you have a div/paragraph/other element with an id, design it without Flash so it's functional. Then you add SWFobject, and the content is replaced by the Flash if it's supported. I wouldn't use a link though, that would potentially put a block level element inside an inline element and would all be linked.
<div id="flash-placeholder"> <!-- or p or .... --> <a href="http://get.adobe.com/flashplayer/"><img src="http://www.adobe.com/images/shared/download_buttons/get_adobe_flash_player.png" alt="get flash player"></a><br> All this will get replaced by Flash </div>
