In other words: this processor doesn't support frequency scaling, so to 
pretend it does (as the kernel used to) was wrong.  If you want 
frequency scaling, buy a system with a processor that supports it.  
There is no software solution to this problem, since the hardware just 
doesn't do what you want it to do.
