I totally agree with John and would add: * is there something that the rest of us can do to help? I am particularly interested in keeping armhf (Cortex-A8 specifically) supported, and while it is not much, I have been contributing to the linux kernel in connection with these machines, and I am looking for ways to contribute more in Debian too.
