Probably this isn't specific to a gentoo build and would happen just
the same with a kernel.org build. So if it is a bug, it is probably an upstream bug.
However, unless it used to work, or something bad happens,
this is sort of an academic failure. I suppose if you ran Windows
on the box and it displayed a changing temperature via ACPI
but Linux does not, then it would be more interesting.
It would be good to verify that ACPI events in general
are working on the box -- eg. the power button etc -- as a failure
there would also be more interesting than unchanging temperature.
