I've made some experiment with my BIOS settings, and I'm happy to  
repport that EST seems ok with my CPUs :

cpu0: <ACPI CPU> on acpi0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
p4tcc0: <CPU Frequency Thermal Control> on cpu0
(repeat for CPU 1-2-3)

I've had 3 settings to play with. One of them was for enabling  
processor power management. The second one was about "C1" versus "C1  
enhanced", and when switched to "enhanced" my power supply started to  
emit a very strange high pitch as soon as FreeBSD finished booting,  
and stopped as soon as FreeBSD was unloaded. The last one was about  
disabling or enabling "GV1/GV3 only". This one was the good one for me.
My current dev.cpu.0.freq is 125 MHz, I'm monitoring CPU temp. too,  
but it will need some time to see if CPUs are running cooler.

thank you all for your help,

Pat
