I got bored, here ya go this should work just fine. Add this to your nightmare class:

		public static void Initialize()
		{
			EventSink.Login += new LoginEventHandler( EventSink_Login );
		}

		private static void EventSink_Login( LoginEventArgs args )
		{
			Mobile m = args.Mobile;
			IMount mt = m.Mount;

			if ( mt != null && mt is Nightmare && m.Skills[SkillName.AnimalLore].Value < 100 )
			{
				m.SendMessage("Place reason for dismounting here");
				mt.Rider = null;
			}
		}
