I believe it means that your ASL does not define ThermalZone object. You
might be able to cobble together one yourself by looking at the example
in the ACPI spec (12.5.1 on page 292 in version 2.0c), provided that you
can figure out how to measure temperature and how to control fan from
the rest of your ASL. I was lucky and stumbled over both while looking
through it. Your mileage may vary.

Also, I had ThermalZone to start with, so I only had to define fan
devices and ACx, ALx objects, hence I really could not offer much help
on building thermal zone from scratch. Sorry.
