well, if you registered the sidebar properly in functions.php you can use it like this.... create the new sidebar file and name it sidebar-something.php
Example:
here's the code from my functions.php
if ( function_exists('register_sidebar') )
register_sidebar(array(
'name'=>'Sidebar',
'before_widget' => '<li class="widget" id="%1$s"><div class="widgetBG">',
'after_widget' => '</div><div class="widgetBottom"></div></li>',
'before_title' => '<div class="widgetTitle">',
'after_title' => '</div>',
));
register_sidebar(array(
'name'=>'TopWidget',
'before_widget' => '<li class="topWidget" id="%1$s"><div class="topWidgetBG">',
'after_widget' => '</div><div class="topWidgetBottom"></div></li>',
'before_title' => '<div class="topWidgetTitle"><span class="topText">',
'after_title' => '</span></div>',
));
this creates 2 sidebars.... one named Sidebar, and one named TopWidget (don't get confused by the before/after widget and before/after title, that's formatting stuff that I use)
After that, I created two files... one was just the standard sidebar.php, and one was named sidebar-topWidget.php
now, I have registered 2 sidebars, and I have created them. To call them I do this:
<?php get_sidebar(); ?> calls the normal sidebar, the one named sidebar.php, I'm pretty sure this is how kubrick calls the standard sidebar
to use my second sidebar, I call this:
<?php get_sidebar ('topWidget'); ?> this calls up the second sidebar, which in my case was named sidebar-topWidget.php
