if you do
~$ glxgears
that will stress your GPU and you should see the temp raising on one of
those 3 unknown, i think i did this already and found they where not
raising...
see the thinkpad i'm using at this moment is a T61p with nvidia, so ibm-acpi
reports GPU and it does give a reading, but also nvidia's got it own sensor
and also reports some temp readings, which funny enough is different from
the one reported by imb-acpi, the nvidia one always report like 10 more... i
personally keep an eye on the nvidia one....
