[PLUG] abit AI7 - acpi, ht


-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello all,

I just purchased a new motherboard, an Abit AI7. The specs look really
good, I've read about the 'wonders' it can do with sensors that have
little to no support in Linux, and with a couple of exceptions it works
fine. Perhaps someone else has this motherboard and/or experienced similar
problems.

1. The motherboard, as well as the P4 processor are HT capable. I have
configured SMP and HT capabilities in the kernel, yet I do not have HT.
Why?
2. acpi ALWAYS prints out 20C (68F). The BIOS utility has nice sensor
printouts, so the sensors _do_ work. It can read data from the bios,
because the alarms change in /proc as I change them in the BIOS. Why can't
I read the real temperature, and where is acpi reading the 20/68
temperature??

Another, not-so-urgent question was if anyone get lm-sensors to actually
work with the built-in sensors? After loading the proper modules I receive
the following information, which is pretty much _all_ wrong:
