Ahh, this is too much trouble to make it optional then :)

That would be more controversial I guess as we may want an unsigned int return
type for frequency.

I think we can do two things here:
- Just enable the sysfs attribute all the time ?
- Make it optional based on some static cpufreq driver flag ?

I would just enable it for everyone I guess.
