I have always wondered about /proc/acpi/thermal_zone.  I noticed that
on some servers, the files exist, but on others, that directory is
empty.  I guess this is dependent on whether the BIOS exposes the
information to the kernel?  Or are there modules that I need to
install to get it working?

Thanks,

Bernard
