Moving your page file to your usb drive would be a terrible idea. The whole point of the ready boost in vista is to make accessing small files that are commonly used really fast. It's basically a page file for a page file. Hard drives have a lot higher access and through put rate for sequencial data, but are terrible when it comes to small "random" bits of data. Flash drives are a lot better for the small stuff. Hence, the readyboost to speed up.
I don't even know if that would be an option to move it to the drive. Your system would probably crash if your drive were disconnected prior to windows shutting down.
