Dwarf barbarians, movement and medium armor

[Ogre Mage]

Can a dwarf barbarian with fast movement still move 30 while wearing medium armor? Or does it knock them down to 20? I am confused on how the dwarf's "encumbrance negation" ability works.

In 3.0, your dwarf would be slowed down to 20 feet if he put on medium armor.

In 3.5e, A dwarf barbarian in medium armor would still move at 30 feet, because dwarves are not slowed down by armor or encumbrence. If your dwarf put on heavy armor, however, he would drop to 20 feet, because heavy armor disables a barbarian's fast movement ability.
