The etymology fairly strongly suggests that a-theism is a lack of belief in theism, and a-gnosticism is a lack of belief in gnosticism.
Actually, the etymology of agnosticism is rejection of gnosis, which is rather broader than the gnostics. We know that because Huxley said so when he coined the word in 1869. That’s also exactly the meaning RobinZ gave.
