Description of problem:
It seems currently impossible to revert back to automatic frequency scaling
after manually setting the frequency. The 'Automatic' radio button is insensitive.
The radio button should be sensitive, and checking it should just switch the
governor back to ondemand.
Version-Release number of selected component (if applicable):
This seems to work better now (though the UI is still sort of gross). Anyway,
feel free to reopen if you still encounter problems.
