Well, from just a quick look at BaseCreature, I found this:

		public BaseCreature(AIType ai,
			FightMode mode,
			int iRangePerception,
			int iRangeFight,
			double dActiveSpeed, 
			double dPassiveSpeed)

which leads to this:

			SpeedInfo.GetSpeeds( this, ref dActiveSpeed, ref dPassiveSpeed );
