dmesg output from 11.1 showing thermal is seen and used

User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.2) Gecko/20090730 SUSE/3.5.2-1.1 Firefox/3.5.2

HP updated the bios for several dv series laptops. This enabled thermal management and other acpi fixes for linux. In the 2.6.27 kernel, cpu temp is read as a valid value. In the 11.2 kernels (30 and 31) this feature is broken.

Reproducible: Always

Steps to Reproduce:
1.install 11.1 on a HP laptop with the bios update for linux thermal and acpi
2.cpu temp is valid and shown. thermal events work.
3.install 11.2 MS5.
4. thermal events are not seen and acpi reports that the value in dsdt is invalid
Actual Results:
11.1 -- thermal management works.
11.2 -- thermal management does not work

Expected Results:
with bios update, the cpu temp should be seen and thermal management should work.
