Those patches do nothing to solve the problem. They simply enable polling in the
event that the ACPI subsystem does not provide a _TZP method (which, apparently,
the nx 6125 DSDT does not). You can accomplish the same effect with much less
ado, by simply echoing 5 into each of
/proc/acpi/thermal_zone/TZ[1-3]/polling_frequency. Polling won't work, I tried
it a long time ago. It makes things worse than asynchronous mode.

The other patches are simply for diagnostic purposes. I have tried the kernel
patch and my results are posted at bugzilla.kernel.org (#5534). There is also a
DSDT diagnostic patch which will echo messages whenever thermal events are
generated. I haven't tried this. Optimally, the developers need to get their
hands on one of these machines and observe this behaviour first hand...
