You can try another approach.
If you sort your links by category, such as "Blogroll", "Good Sites", "Whatever"..., you can do the following:'
o Delete the wp_list_pages() section from your sidebar
o In the Links/Link Categories add a new link category named "Pages"
o Go to Manage/Pages and copy the permalinks for the pages you want to list.
o Now go to Links/Manage and add the permalinks to the "Pages" link category.
The links to your selected pages will show up in a separate list block in your links list.
I've made an example for you at http://petitpub.com/blog.
Far down at the right side under Blogroll and Friendly Sites, you find the Pages heading, with one link to my About page.
