Hello,

I have a FreeBSD box running 6.2R on 2 dual core Xeon LV (sossaman).  
Vanilla ACPI is supported, and powerd works great. But advanced  
features are unavailable because cpufreq won't recognize my CPUs. For  
example, as acpi will only reduce frequency and not voltage, the CPU  
remains at the same temperature.
I've read on http://www.daemonology.net/freebsd-est/ that "est" port,  
from where comes cpufreq's "est", won't handle multiple CPUs. Is that  
still true ?

dmesg (part of):
FreeBSD 6.2-RELEASE #0: Sun Jan 14 20:48:28 CET 2007

(same for cpu1/2/3)

Is there anything I can do to make "est" work with the sossaman CPU ?

thanks in advance,
