Yes, correct.

The generic trip point handling in the acpi thermal driver is another 
story. Some code reorg and cleanup should be done before. I have a 
series for that but I need to test it more. That is the reason why it 
will be submitted after this series is reviewed, so the changes will be 
focused on the acpi thermal driver only.

I have a laptop with acpitz but only the critical trip temp.
