For those who for some reason can't/won't upgrade to WP 3.0, it might be useful for someone to make a quick "3.0 theme compatibility" plugin that basically does this:

if ( ! function_exists('comment_form') ) {
	function comment_form() {

...for each of the new WP 3.0 theme functions.

You could also do this if making a 3.0 theme that you want to make backwards compatible.
