I saw it when I knew what to look for. Sorry for the noise. Just want to
let you know that everything works perfect on a Asus CUV266-DLS. Have to
use the third alternative for computing cpu-temps. (compute temp2
(@*60/43)+25,(@-25)*43/60) Might perhaps add that in the example config,
if anyone cares.

When I run three burnP6 on Linux I get almost exactly the same
measurements as when I do the same on Windows. So everything looks just
perfect :)

Again, sorry for the noise. By the way, gkrellm reads right from sysfs,
without the need for updated lm-sensors user-space tools. (But I guess
you knew that).

Thanks for your help and great work!

Best regards,
