I've heard this off a number of admins. There's no check for Knight's skill Riding in battle.c, when calculating weapon attack, to check if the player is riding and is wearing a spear, thus nullifying the size fix.

Mounted characters also attack at half the normal speed, but this penalty can be reduced or offset by levels in Cavalry Mastery. While mounted, the size modifier of spear vs. medium size is 100% instead of 75%.
