I think I've fixed the spontaneous reboot and system hang problem I've been
having with FBSD 6.1 & 6.2 as described in earlier threads of the same
subject. I'm now using FBSD 6.2 to send this message.
What I did was to set a hint in /boot/device.hints and also /boot/loader.conf
to disable acpi
and then I set a hint to enable apm

and in /boot/loader.conf, I put
The messages log shows that APM is being detected, and the computer now fully

I've a suggestion. It would be nice if freebsd could try to detect if acpi is
supported on the computer in which it is being installed, and if none is
found, it should completely disable acpi and then check if apm is supported.
It should then set the appropriate settings to enable the correct power
management support for the computer. This would prevent this particular
spontaneous rebooting and hanging on old computers like mine which are
pre-acpi but have apm support.
So far, I haven't had any problems using KPPP. I've been up for over an hour
and I've never been able keep the computer up for this long before making
