I powered by connecting IOIO Vin <-> Driver Vmot. Despite the specs, I can verify that 2-cell works OK even when the battery is low. In hindsight, since you've pointed out the out-of-spec usage, I would probably do things differently.
If I were you, I'd probably just use the drivers as is, and if there's a problem, move to a 3S LiPo (make sure the power lines are short-as-possible). Don't be too hard on Pololu, they're offering good products at great prices and dealing with returns is probably a conscious compromise they've made, which is reasonable in the vast majority of cases. Just my $0.02...
