Hi Dan I understand you because I have exactly the same problem with the new battlefront!
I am also looking for an answer although I have a 4th generation intel I7 quad core, 8 GB RAM, windows 8.1 64-bit, intel HD graphics 4600. But when I try to find updates for the driver, I can't find a good one who is compatible with my system.
You can try to download the latest driver version from our web page Intel® Download Center, filter according to your system specifications. However, please bear in mind the following information http://starwars.ea.com/starwars/battlefront/news/star-wars-battlefront-community-update-5, this link is from the developers of the game and as you can see the requirements are very demanding even the minimum requirements are demanding. If you're running the game out these requirements any issue you might get will be expected.
I think that it's not a problem with the drivers. It's because you only have an Intel HD Graphics 4000 as a graphic processor. You don't have a true graphic card (NVidia or AMD).
So it's not enough powerful for your game... and lots of other games. I'm sorry for your son, but without a true graphic card, you won't be able to run this game
Here is the system requirements : http://www.game-debate.com/games/index.php?g_id=8081&game=Star%20Wars:%20Battlefront
Even me with my poor NVidia GeForce GT 740M on my laptop, I think that I would be very limited...
Edit : Oops ! I just saw that Intel answered you the same thing ^_^
SuperLumberjack thank you for sharing this information.

the game works on an iris 5100
there is a bug in the current hd 4000 driver that prevents the game from working this also affected the beta Intel HD 4000 on Star Wars Battlefront
Intel does not want to make any more drivers for hd 4000 https://downloadmirror.intel.com/25313/eng/ReleaseNotes_GFX_188.8.131.5276.pdf
