There was a race in the Star Wars D20 Saga Edition RPG called the Codru-Ji, which were basically four-armed elf/humans. I never played with them myself so I'm not sure if they're balanced, but it might be worth looking into. It was in the Legacy Era Campaign Guide, which of course, is out of print, but you might be able to find a copy online or on some kind of SRD.
Or, you could always come up with a new race for him. Call it a "goro" after the villain from Mortal Kombat or something.
+2 Strength, -2 Intelligence, -2 Wisdom
Medium: Goros are Medium creatures and have no bonuses or penalties due to their size.
Slow Speed: Goros have a base speed of 20 feet.
Intimidating: Goros receive a +2 racial bonus on Intimidate skill checks due to their fearsome nature.
Extra Limbs: Goros have four arms, allowing them to make attacks with each of their hands. The usual penalties for two-weapon fighting apply, except the goro may make up to three off-hand attacks. Using a light weapon and taking the two-weapon fighting feat reduce these penalties, as usual. In addition, a goro only needs to use two hands to grapple an opponent, leaving them open to use their remaining hands for attacks.
Magic Sensitivity: Goros are particularly prone to magic, suffering a -3 to all saving throws against magical effects.
(Okay, I made up that last one just to make it balanced a little better. It was off the top of my head; I'm sure someone else could do much better. Anyway, there's one solution.)
What is suggested above just sounds really harsh to me, but is overall a good idea. If you do want to try something like this make sure that you mention that you are doing it as a trial basis and they may need to change it later.
Two negative abilities and a -3 to most saving throws? Ouch
+2 str, but -2 int, -2 saves would be more then enough I'd think.
I'd also add improved grapple as a bonous racial feat.
alchemists and synthesist summoners can do it.

If you think he would be happy with them I give a +1 to the suggestion of directing him towards classes that can already do this. Particularly the summoner, who can more or less have those extra arms all the time.

Yeah. It was off the top of my head, and I just wanted to balance out the fact that this character would be able to get four attacks at first level with a full action.
Well, unarmed strikes, including those within a flurry, can be made with any part of the body.
Even with just 2 hands, once he gets past any restrictions based around the grapple maneuver, he can kick or headbutt or whatever else he can think of that is reasonable.
TRI-KREEN ! ! !
Always loved those. Really wish PF had been able to include them. I'd suggest a home game conversion of this wonderful race.
