I know that T.D. Ameritrade doesn't and I wonder if any do if it's mainly because the variable margining of futures options is inherently in conflict with IRA rules?
Actually TD Ameritrade does allow you to use futures in your Traditional IRA but they have minimum requirements in order to qualify. I actually have one of my IRA accounts there and trade futures in it now. There are other firms that have allowed it in the past too like IB but I think they ended up changing after their forex debacle.
