You really should be asking people who work for Amazon. I suspect that nobody who regularly reads this mailing list knows the answer. (If you look through the MAINTAINERS file, you'll find there are a few kernel developers who do work for Amazon, or at least, have @amazon.com email addresses. Try asking some of them.) But even if the Kindle firmware gets changed (which I doubt will happen), we would still want to support all the old devices that aren't running the updated firmware. Alan Stern
