Eventually, she was quiet for a minute or so - could have been half a minute, after an hour and a half it wasn't quite so important to me. So I took her outside, brought her back in, and played with her for 15-20 minutes to tire her out. She got sleepy, and I put her back in her crate. She came right out, I gave her about a minute's more play, and then put her in and she settled right down.
So, the secret trick is that if you can avoid it, never put your puppy away when she's excited or full of energy!
