Ok, that explains things, so how to get it working, are there any

Please don't top-post.

I don't think there is an acpi driver available; most of the time there isn't.
Also, looks like the acpi thermal module isn't loaded, meaning acpi may not export
the necessary thermal information at all.

acpi drivers are highly board and vendor specific, which means that typically no one
really bothers to write a driver for it, including board vendors. Besides, most of the time
much of the available information from the chips is not exported to the user through acpi,
so even if you had an acpi driver you would likely end up with limited or even no information.

Only option I could see (besides enabling the relax option) would be to disassemble the DSDT,
check what is available, and if there is anything write a driver yourself to access it.
By disassembling the DSDT you would also see what kind of risk you could run into by disabling
the region conflict checks.

You do see the answer above. You have an ACPI resource conflict.
