Why would IBM put a "thinkpad" button on their laptops, create a linux
tool to use it, and neither release the tool for general use nor tell
people how to use it? Why do companies refuse to release info on
anything?

That's assuming that it uses the same amount of power for the same
amount of computation, which is probably untrue. CPUs wouldn't be the
first thing to be less efficient as they go faster.
