I believe those are both hard coded into the engine too. If you gave horses less charge I believe they'd have more trouble running through infantry, though. I've never really seen a problem with the current system, horses usually down pretty quick when you run right into a mob of infantry.
Athletics already makes you pretty darn fast. With 10 athletics and no armor you can practically catch horses. If you wanted to make armored troops move faster in general, you could decrease weight on armors.
