Per core frequency control

Hi,

I was reading through cpufreq(4) and in the bugs section it mentions that per 
core (or CPU) frequency control is not supported.  That all cores/CPUs have to 
be at the same speed.  

What is the reason for that?  

Is it an infrastructure problem with FreeBSD or has it just not been 
implemented?  

And how will the recent work on event timers (and a "tickless" kernel) impact 
on this problem? 

Regards,

David
