People seem to have a thing for dropdowns.  I attached a patch to bug
1189 that adds dropdown support to wp_list_pages().  Use it like so:

wp_list_pages('style=dropdown');

The list style can be had like this:

wp_list_pages('style=list');

If no style is specified, list is used.

Anyone want to try it out and spruce it up?  It's currently very rough
draft.  Any options we need to add?
