Maybe it has also some code to access the chip? In /proc/acpi I can read only one temperature, while the chip measures three temperatures, fan speeds and voltages. This is desktop pc with ASUS A8N1-E maniboard, athlon64 and nforce4 chipset.Try the asus_atk0110 driver, it handles the ACPI hwmon interface on Asus motherboards. If it does not work then please send a dump of your DSDT (/sys/firmware/acpi/tables/DSDT).
