Hmm, so it should be enabled then.

Hmm, if you say it worked before 3.2, then it didn't use ACPI the way it
does today so that it fails on your box.
Here's what I got on my box:
[ 0.000000] ACPI: RSDP 00000000000f6620 00014 (v00 GBT )
[ 0.000000] ACPI: RSDT 00000000cfff3000 00038 (v01 GBT NVDAACPI 42302E31 NVDA 01010101)
[ 0.000000] ACPI: FACP 00000000cfff3040 00074 (v01 GBT NVDAACPI 42302E31 NVDA 01010101)
[ 0.000000] ACPI: DSDT 00000000cfff30c0 04C8E (v01 GBT NVDAACPI 00001000 MSFT 0100000C)
[ 0.000000] ACPI: FACS 00000000cfff0000 00040
[ 0.000000] ACPI: SSDT 00000000cfff7e40 004CE (v01 PTLTD POWERNOW 00000001 LTP 00000001)
[ 0.000000] ACPI: HPET 00000000cfff8340 00038 (v01 GBT NVDAACPI 42302E31 NVDA 00000098)
[ 0.000000] ACPI: MCFG 00000000cfff8380 0003C (v01 GBT NVDAACPI 42302E31 NVDA 01010101)
[ 0.000000] ACPI: APIC 00000000cfff7d80 00098 (v01 GBT NVDAACPI 42302E31 NVDA 01010101)
and the SSDT table contains, when disassembled, all those _PCT and _PSS
objects. (I guessed it by the OEM Table ID "POWERNOW" :-)) They look
something like this:
Name (_PCT, Package (0x02)
{
ResourceTemplate ()
{
Register (FFixedHW,
0x40, // Bit Width
0x00, // Bit Offset
0x00000000C0010062, // Address
,)
},
...
each in a _PR - processor - scope. (Boy, do I hate ACPI!).
Now, if we look at your ACPI tables:
[ 0.000000] ACPI: RSDP 00000000000f7170 00014 (v00 GBT )
[ 0.000000] ACPI: RSDT 00000000c7de3000 00034 (v01 GBT GBTUACPI 42302E31 GBTU 01010101)
[ 0.000000] ACPI: FACP 00000000c7de3040 00074 (v01 GBT GBTUACPI 42302E31 GBTU 01010101)
[ 0.000000] ACPI: DSDT 00000000c7de30c0 064A2 (v01 GBT GBTUACPI 00001000 MSFT 03000000)
[ 0.000000] ACPI: FACS 00000000c7de0000 00040
[ 0.000000] ACPI: HPET 00000000c7de9640 00038 (v01 GBT GBTUACPI 42302E31 GBTU 00000098)
[ 0.000000] ACPI: MCFG 00000000c7de9680 0003C (v01 GBT GBTUACPI 42302E31 GBTU 01010101)
[ 0.000000] ACPI: APIC 00000000c7de9580 00084 (v01 GBT GBTUACPI 42302E31 GBTU 01010101)
the one missing is the SSDT table so either your BIOS is not providing
the it, or P-states are hidden in some other table or ...
Your BIOS is from 2008. Can you get a newer one from Gigabyte and update
it, if possible?
