I am having a similar problem in WordPress 3 with a multisite install. You seem to have got further than I have though.

I think your problem is in the line:

$new_rules = array('list/(.+?)/?$' => 'index.php?list=$matches[1]');

have you tried changing it to the following?

$new_rules = array('list/(.+?)/?$' => 'index.php?pagename=list&list=$matches[1]');

I have implimented your code on my site and it is working. It takes you through to a profile page and allows me to display users profiles (we’ve also build an advanced search in to it). Code is below if it helps 🙂

All the best,

Steve

function nd_add_rewrite_rules( $wp_rewrite ) {
	   $new_rules = array('profile-page/(.+?)/?$' => 'index.php?pagename=profile-page&id=$matches[1]');
	   $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
	}

	function nd_query_vars($public_query_vars) {
	   $public_query_vars[] = "id";
	   return $public_query_vars;
	}

	function nd_flushRules(){
	   global $wp_rewrite;
	   $wp_rewrite->flush_rules();
	}

	add_action('generate_rewrite_rules', 'nd_add_rewrite_rules');
	add_filter('query_vars', 'nd_query_vars');
	add_filter('init','nd_flushRules');
