Indeed, the DSDT contains an invalid active trip point,
which is a BIOS bug.  The linux complaint is correct,
indeed, we should really highlight it with [Firmware Bug].
The question is if Linux has somehow
started to get confused by this, when it didn't in the past.

These suggest that this BIOS isn't fully baked --
is it a production level BIOS?  Is there an update available?

When /proc/acpi/fan was present, what was in it?
Looking at the tables, it seems that it should be empty
back when it existed, and we deleted it entirely in 2.6.38)
and we deleted it entirely in 2.6.37)

Can you describe the failure in more detail?
What does it take to over-heat the laptop.
Can you hear the fan spinning.  Is the sound
and the ability of the laptop to overheat changed
if you boot the old kernel?
