custom sidebar for 2010 child-theme

Hi all,
I have made a child-theme for 2010 that is looking pretty good, but now I cannot figure out how to register a custom sidebar in functions. Somehow its different from the way I used it in wp2.9.2.

I have made a custom page template and named it page-about.php (for the about section). the devsite is https://www.sanneart.com/draper/
Within that I have put <?php include (TEMPLATEPATH . 'sidebar-about.php'); ?>

then I know I have to register the sidebar in the functions.php ( in my child theme)
I have tried this

register_sidebar( array(
		'name' => __( 'about sidebar'),
		'id' => 'sidebar-about',
		'description' => __( 'sidebar for about pages' ),
		'before_widget' => '<li id="%1$s" class="widget-container %2$s">',
		'after_widget' => '</li>',
		'before_title' => '<h3 class="widget-title">',
		'after_title' => '</h3>',
	) );

I can’t get it to work. Can anyone help?

thanks
