Thermal Zones

(from Gnome Bugzilla #347406<http://bugzilla.gnome.org/show_bug.cgi?id=347406>
)

Although data for acpi thermal zones is exposed through /proc/acpi, and
potentially sysfs in the near future, it is not currently being exposed in
HAL. We'd like to rectify that...

What do you all think? Whats missing/unclear?

Thanks a lot!
