It's important to let your son know that you are on his side and ask him how he wants to take care of it. Of course he will say he doesn't know, so provide him with a few examples from him talking to them all the way up to hitting someone upside the head with a 2x4. I say this so you will be able to gauge his emotional state and frame of mind.
Walk him through the ramifications of each choice, understanding that talking just may be impossible to resolve the matter. You must be realistic. You must also understand the law and not tell him to do something that gets him in a legal jam. The post that suggests you talk to the school and document your discussions are great. As a last resort, but just may be as necessary, talk to the parents of the bullies.
Your son just may have to learn know to deal with this now, because child bullies usually become adult bullies.
