Take a closer look at your patch, we don't want to disable hdparm as a whole from running,
we just want to be able to "opt out" of this global APM config, which you can't do without
editing the function file /lib/hdparm/hdparm-functions. A good compromise would be
to add smarts to the config file parser which allows one to disable the global apm policy.
It could be as simple as setting apm = skip and then dropping it completely from the argument
list. hdparm is a very necessarily utility for things like disabling the cache and other things.

Your approach would leave the above average user scratching his head because they would
make changes in /etc/hdparm.conf and it just wouldn't happen ever.
