Do you know how to read and override DSDT?
Here is a description
http://www.lesswatts.org/projects/acpi/faq.php

You should cluster above mentioned functions with lines like:
Store ("Variable VARIABLE is:", debug)
Store (VARIABLE, debug)

Maybe we get clue why 0x1D GPEs do not end as thermal notifcations even they
possibly should.

The problem is that Dell in general (and especially at these places) makes a
lot use of SMI calls. SMI triggers BIOS code getting executed behind our back
(impossible to track in OS what is done there).

There is the Dell dcdbas driver which is passing userspace requests to the
kernel, converts them into a SMI and triggers BIOS code.
You should double check whether this one got loaded and if yes try without.
Best make sure that it never got loaded, e.g. by temporarily moving the .ko
driver in /lib/modules/`uname -r`/... away.
Best you always have a look at /proc/acpi/event, there should pop up thermal
events if things start to work.

Or maybe you need the userspace app (more unlikely). I do not know it, I expect
it is a binary Dell app, but maybe it's even open source, you should be able to
find it.
