actually since the footer is a row in a table, this is probably the easiest long term method since it will survive theme updates.
add the following to 'Footer: Content'
HTML Code:
<div id="myfooter1"> this is footer 1</div>
</td></tr>
<tr><td id="myfooter" colspan="3">
<div id="myfooter2">Copyright © %current-year% %home% - All Rights Reserved</div>
this adds a div to the current table row with the ID 'footer', ends that table row and starts a new table row with the id 'myfooter'. The colspan="3" assumes you have a right and left sidebar, you'll need to adjust that to your setup.
You will need to style each table row separately - The first will use the theme option settings, the second you will need to add to the CSS Inserts option. Try adding this to the CSS to get an idea - the borders show you the defined area of each element
HTML Code:
#footer {border:solid 1px red; margin-bottom: 20px;}
#myfooter1, #myfooter2 {border:solid 1px tan; margin-bottom: 20px; height:40px;}
#myfooter {border:solid 1px blue;
background-color: #FFFFFF;
color: #777777;
font-size: 95%;
height: 52px;
padding: 20px 0 0;
text-align: center;
width: auto;}
