But it probably wouldn't be. We aren't talking about "fixing" the problem, we're talking about providing an option. It just so happens that the option is a kludge fix for some systems. Actually "fixing" the problem requires making the driver aware of drive spin downs and making it deal with it transparently instead of screwing up by passing an error to higher level code. Disabling the spindown is not what I'd call "making the code 'green aware'"...
