Comment:

 You could use a wrapper class:

 {{{
 class My_Functor {

   function __construct( $cb, $args ) {
     $this->cb = $cb;
     $this->args = $args;
   }

   function invoke() {
     $args = func_get_args();
     return call_user_func_array( $this->cb, array_merge( $args,
 $this->args ) );
   }
 }

 $extra_args = array( 'value1', 'value2', 'value3' );
 add_action( 'some_hook', array( new My_Functor( 'my_callback', $extra_args
 ), 'invoke' ) );
 }}}

 This way, we can keep add_action() blazing fast for the normal case.
