This is what I use on one of my sites, then just add a custom field on each post/page you don’t want autop on.

custom field name = disable_autop, value = whatever, true is fine.

function disable_autop() {
global $post;
$disable_autop_var = get_post_meta($post->ID, 'disable_autop', TRUE);
//var_dump(get_post_meta($post->ID,'disable_autop', TRUE));
if ( !empty( $disable_autop_var ) ) {
remove_filter('the_content', 'wpautop');
}
}
add_action ('loop_start', 'disable_autop');

Any Thoughts?
