From what I understand, the fall knocked out the AT-AT's shield generator, allowing it to be destroyed by the Snowspeeders. Also, when someone refers to "armor", it doesn't always mean just the physical structure. It can also refer to any protective shielding, since it is in effect part of the vehicle's defenses.
Make sense?
Nice try, but the AtAt's have no shield generators. And If they did, how was Luke able to climb up and cut through the bottom hatch?
