The sysctls are dev.cpu.X.freq.  For now, you'll only ever see a 
dev.cpu.0.freq and changes to it will be made to all processors.  (I'm 
still improving MP support but that's how it will be.)  In the future, 
once the hardware drivers are improved to support independent MP 
frequencies, the framework can easily be updated to export the sysctls 
on all cpus.  This change is about 10 lines of code.

Info about the framework is in the cpufreq(4) man page.  The acpi 
projects page is where work is currently being noted.  I haven't updated 
it recently though but once I get the next round of commits in, I will.
