Thank You for Your replies :)

I didn't :)
Actually I have read all the documentation / relevant google groups
threads i could find befor mailing freebsd-acpi@.

I missed that, true, now i run not patched STABLE. However, my problems
remain:
1. With cpufreq framework, I tried powernow module (with powerd of
course). Problems:
a) sometimes powerd 'misses' the temperature jumping from somewhere
near _PSV to over _CRT resulting in system shutdown.
- I tried to change the interval time but it didn't help much,
I'll try to check it better though.
- I tried to lower the _PSV value somehow, but I cannot -- either
with sysctl or asl acpi tweaking.
- I tried to set ACx levels to better cool my cpu, but failed to
set them (they are all set to -1 and no mention of them in the acpi asl)
b) when the system is idle, and the temp is about 47-55 degrees
Celsius, the acpi_ppc module seemed quieter (it turned off completely i
guess). powernow modules is running fan at lowest, but still audible and
quite distracting level
2. With acpi_ppc, the cooling is well driven, but acpi_ppc does not
throttle cpu when _PSV is hit resulting in _CRT shutdown.
- I think acpi_cnq (as acpi_ppc to cpufreq port) would join
acpi_ppc's fan-driving and cpufreq passive cooling, but It panics on
kldload (a bad free).
- Is acpi_cnq integrated obsoleted by powernow module?
