It doesn't mean that ACPI doesn't get the temperatures from the DME1737 chip though, it could be adding some arbitrary offset. Can you please send me your DSDT table in private? I'll take a look. I also have an experimental (but safe) patch detecting possible conflicts between ACPI and hwmon drivers.

Many distributions load it by default, which makes sense for laptops, but way less for desktops IMHO. > (...) > lisa:/home/jba# uname -r > 2.6.18-5-k7 > > Its a stock debian etch kernel. Except for the dme1737 driver, of course ;) -- Jean Delvare
