Well, my temp is about 6-9°C hotter in idle mode, but with current
kernels APIC (and no CPU diconnect) seems to be more stable than PIC and
CPU Disconnect with my nforce. I at least don't have problems with
forcedeth driver and current acpi.

I remember Jesse Allan sending some lspci outputs to Bart to investigate
the BIOS fix. I wonder what has happened to it. I tried to do a
comparison with my values, but due to lack of some smart tools to show
what is common and what is not (diff is not very suitable) it is very
hard, esp if you have no knowledge about the actual meanings of those
parameters.
