remove_filter( ‘the_content’, ‘wpautop’ ); only for certain post types

Hook into the_content before the wpautop filter has been called, check the post type, and remove the wpautop filter, which is added in wp-includes/default-filters.php with the default priority 10:

add_filter( 'the_content', 'wpse_82860_remove_autop_for_posttype', 0 );

function wpse_82860_remove_autop_for_posttype( $content )
{
    # edit the post type here
    'post' === get_post_type() && remove_filter( 'the_content', 'wpautop' );
    return $content;
}
