Just change body like this:
<body>
<div id="wrapper">
<div id="content">
<div id="cell-left">
<div id="content-left">
<ul>
<li><a href="#">menu item 1</a></li>
</ul>
</div>
</div>
<div id="cell-right">
<div id="content-right" style="position:relative">
Lorem ipsum dolor ... bla bla bla
<div style="position:absolute; left:-185px; bottom:10px; width:180px">This is the div that needs to rest on the bottom vertically align on bottom</div>
</div>
</div>
</div>
<div id="footer">sdsd</div>
</div>
</body>
Actually I've changed just these lines:
<div id="content-right" style="position:relative">
Lorem ipsum dolor ... bla bla bla
<div style="position:absolute; left:-185px; bottom:10px; width:180px">This is the div that needs to rest on the bottom vertically align on bottom</div>
</div>
