you may want to try to set hw.acpi.cpu.cx_lowest=C4 here.

I don't see any thermal zone.  How are you able to determine the current
temperature for this model?
It's also strange that one is not able to scale frequency and voltage
from the est driver (included in the cpufreq.ko module).

ditto.  Try hw.acpi.cpu.cx_lowest=C4

For both of your laptops, you can set this sysctl via your
/etc/rc.conf

Do a man rc.conf and look for 'performance_cx_lowest' and
'economy_cx_lowest'.

It's not that high, especially if frequency and idle power saving (this is the
C? stuff) are not turned on.

Sound like only acpi_throttle (or p4tcc) is used, but no est.

Could you please try to include the following to your loader.conf:

cpufreq_load="YES"


Note that it's not possible ATM to 'kldload cpufreq' for the enhanced
speedstep support.
