acpicpu(4) strangeness

[Dustin Marquess <dmarquess%gmail.com@localhost>]

Sorry ahead of I'm doing something wrong.  I did some searching around
and reading before posting, but I didn't find anything obvious.

I'm running -current from a couple of days ago.  I made sure that my
config has ENHANCED_SPEEDSTEP, EST_FREQ_USERWRITE, POWERNOW_K8, and
INTEL_ONDEMAND_CLOCKMOD all commented out.  My config also has:

acpicpu*        at acpi?                # ACPI CPU

I have a Supermicro PDSMi-LN4+ board with a quad-core 2.4Ghz Xeon
X3220.  cpuctl output shows:

cpu0: Intel Core 2 (686-class), 2394.07 MHz, id 0x6fb

cpu0: Initial APIC ID 0
cpu0: Cluster/Package ID 0
cpu0: Core ID 0
cpu0: family 06 model 0f extfamily 00 extmodel 00

I believe acpicpu is enabled correctly, as sysctl shows:

hw.acpi.cpu.dynamic = 1
hw.acpi.cpu.passive = 1

However the old est values appear to be wrong:

machdep.est.frequency.target = 900
machdep.est.frequency.current = 900
machdep.est.frequency.available = 900 600

I'm not sure where 600 & 900Mhz are coming from?  Am I doing something stupid?

Thanks!
