No, it's not ancient. With no capabilities that can set or report  CPU
frequency, the OID is undefined.

I may be that the "CPU supports Enhanced Speedstep, but is not recognized."
is really a problem. It says that FreeBSD does not have a table of the EST
setting/energy saving values for that processor. This is not unusual as
Intel at some point decided that these tables were proprietary and stopped
releasing them to the open source community. ACPI should be able to provide
the list of frequencies but it looks like it did not do so. This may be a
bug in BIOS.

Do you see similar messages for all est devices? I am guessing that they
do, but your message does not actually say so.

In any case, the problem is that EST is not attaching and that is cause of
the lack of the OID when P4TCC and throttling are disabled. Since you are
only using it to be sure that the system is running at full speed and re
not running powerd, there is no reason not to enable P4TCC so the OID will
be defined. TCC will not actually be used, so this is the simple solution.

I am concerned that there is now a second report of this, though. It smells
like a BIOS issue,but it seems to work under Windows. Perhaps you need a
BIOS update? (N.B. This is really grasping at straws as I just don't know
much beyond what I have said.)
