If we ever see the status changing, we can also trust the new value.
Maybe we can even trust any value other than 0x07?

OTOH, what happens after resume from suspend to disk?

Also, should we save the fan status on suspend and restore it on resume?
(My take: no. Thermal conditions may have changed, it's best to leave
it at the default.)
