At first, kill acpid, then do a cat /proc/acpi/events
Press the power button, or sleep button, do some ac plugging, unplugging,
etc.  If some of those events are not properly reported, then write to
the ACPI develloper ML list..

If that work, you may have to instruct how acpid(8) will react for an
event.  Look at /etc/acpi (on a debian system).

PS: there may be a trouble with 'old' bios, or even newer in some kind
of compatibility issues, and I think that the correct place to ask
help is ACPI ml dev.

No.  A Pentium II can only support throttling (like any Intel compatible
up to 486 IIRC).  CPUFreq have not integrated throttling support on
i386, apart for the P4 via it's internal clock modulation.

You may have throttling support via ACPI (T-State).  Look at
