The small boulders can not be move unless you catch Cobalion (Mistralton Cave, Steel/Fight, level 42). When you catch it, the blocks won't be there anymore and you'll be able to catch Terrakion (victory road, Fight/Rock, level 42) and Virizion (Pinwheel Forest, Grass/Fight, level 42). This also works in Pokemon White.
