Why make a config option?  Is there any reason why someone would want
to disable this feature, assuming the firmware supports it?

If there is some reason to turn this off, then a module parameter
would make more sense to me -- otherwise a kernel config option means
that a recompile is necessary to change the setting, and distros won't
ship drivers with the option turned on.
