Borked ACPI on nc6400?

[Subhro]

Hello,

I am running FreeBSD 6.2 stable on a HP nc6400 series notebook. I am
having quite a few issues with ACPI.

1. Although the system can be powered off using halt -p, the suspend
to ram states (S1 S3) don't work. On doing:

acpiconf -s 3 I get:

Aug  7 18:31:13 fairlikely-lr acpi: suspend at 20070807 18:31:13

2. I am repeatedly getting errors regarding invalid thermal states:

Aug  7 18:29:08 fairlikely-lr kernel: acpi_tz0: _CRT value is absurd,
ignored (256.0C)

3. CPU Frequency stepping does not work. If I enable powerd, initially
I can see the CPU frequency changing but it hangs randomly. The only
way out is to do a hard reboot.

I am attaching the outputs of sysctk hw.acpi and acpidump -dt.

Please feel free to ask for any further information.

Thanks
