Well,
At our lab we have a lot of i965-based Intel boxes as well as some=20
nForce-4 based ones. I use at home also a nForce4-based one and I=20
realized that none of them equipted qith an AMI BIOS does not show up=20
temperature zones in ACPI.
I had an ASUS A8N-SLI motherboard with AWARD BIOS where I definitely had =

those temperature zones, when I changed the motherboard to an A8M32-SLI, =

BIOS came from AMI and the temperature-zones informations via ACPI has=20
gone. It seemes to me to be an BISO-vendor issue, due to the super IO=20
chip is of the same brand and only a more modern version in the newer MoB=
