But isn't the point of a hardware entropy source that you don't quite trust /dev/urandom?

You have two adversaries. Adversary A have control over your hardware source, and adversary B have control over /dev/urandom. If you XOR them A and B must cooperate to compromise your random generator. You can combine as many sources of randomness as you want, and each increase the difficulty for an adversary to defeat your generator.
