Arguably the most important single hominid trait in easing day-to-day evolutionary pressures has been commerce, which enabled the force-multiplying effects of specialization in the production of the basic resources needed to survive. So to take the thought experiment in a different direction, if you can imagine a (simple) commerce system developing and functioning before a species develops language, perhaps that could be the driver of the intelligence level-off.
