Unable to detect a thermal sensor: lm_sensors and ACPI

HP Pavilion ze5600 laptop, latest Arch kernel, ran sensors-detect and this is the result:

Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.

I tried "sudo modprobe thermal" and although successful there is no thermal entry in /proc/acpi . I also tried adding "acpi_enforce_resources=lax" to kernel boot line without success. I also attempted to insert the i2c-dev module before running sensors-detect, without success.

As I have not tried any other OS on this laptop I am unsure whether it does actually have a sensor but googling around others seem to have been successful. Any suggestions on how to proceed would be most welcome.
