Look for a BIOS update. Even if the updated BIOS doesn't let you change your FSB, it's probable that somebody realized the issue and fixed it in the update.
Don't settle for the lower FSB. You didn't spend your money on that. Someone made a mistake somewhere. Don't OC anything either, since at this point, you're an innocent customer who has broken no service agreements or warranties.
