Yazen,

You generally envision tools like this to only be used when there is a 
problem, and not something that's run critical path on every boot right?

If so, how about doing it in a high level language with easily 
importable libraries like Python?

Then the tools can still be stored "in kernel tree" and distributed with 
distro "kernel tools" packages but you can more easily use them on 
random old kernels too since the binary via /sys/firmware/acpi/tables 
should be widely available.
