Comment(by mwidmann):

 Here's a way around this limitation, I load it from a mu-plugin.

 {{{
 add_action( 'update_option', 'vmh_update_option', 11, 3 );
 add_action( 'delete_option', 'vmh_delete_option', 11, 2 );

 function vmh_update_option( $option, $oldvalue, $newvalue ) {
         global $blog_id;

         if ( is_multisite() ) {
                 $key = $blog_id."-".$option."-blog_option";
                 $value = wp_cache_get( $key, "site-options" );
                 if ( FALSE !== $value ) {
                         wp_cache_set( $key, $newvalue, "site-options" );
                 }
         }
 }
 function vmh_delete_option( $option, $oldvalue ) {
         global $blog_id;

         if ( is_multisite() ) {
                 $key = $blog_id."-".$option."-blog_option";
                 wp_cache_delete( $key, "site-options" );
         }
 }
 }}}
