I would think it wouldn't be that hard to do; just save the book id or whatever and the location/page you're on. Save it to a file on the reader. When booting, if that file exists use it to start the reader program and jump to the saved location.

On the other hand it might be a safety issue; imagine that a specific location in some book causes the reader software to freeze. At least then you could reboot and try again, only to have it freeze. But as it is now at least you have a way out by rebooting.
