Sager NP3760 DSDT - how to enable thermal zoning?

[Bradley Chapman]

(Please CC my e-mail address, I am not a member of this list)

Has anyone managed to successfully modify the DSDT of the Sager NP3760
(a rebranded Clevo M375E/M375W, IIRC) to support thermal zoning and
temperature monitoring?

Compiling the DSDT using iasl 20030918 returns the following errors:

Do these errors have any bearing on the lack of thermal zoning?
