I'm wondering, why acerhdf is even loaded for your notebook, as no MODULE_ALIAS matches:

[...]
MODULE_ALIAS("dmi:*:*Acer*:pnAOA*:");
MODULE_ALIAS("dmi:*:*Acer*:pnAspire 1410*:");
MODULE_ALIAS("dmi:*:*Acer*:pnAspire 1810*:");
MODULE_ALIAS("dmi:*:*Acer*:pnAO531*:");
[...]

Which distribution do you use? Does the distribution somehow autoload acerhdf? Or do you manually load the driver?

Peter, it looks like we support not only Atoms with that driver. Maybe
we should check the cpu specs of the 1810T for example (and google says
there are several different cpu types packaged with those laptops)
before we enforce temperature limits on them...? And let me ask you
this: are all those 1810T* entries in the bios_tbl there because of
noisy fans ...?

Boris, I agree, we really should check the cpu specs. A quick search got me to this page: http://www.hardwaresecrets.com/article/Maximum-CPU-Temperature/143/5 where we clearly see, that the core 2 have much lower critical temperatures. I added all those 1410* and 1810T* entries on behalf of people telling they'd have the fan control working with these lines for some weeks without problems and I didn't care about searching for the netbooks specifications. My fault.

I would propose to enhance the bios_tbl by the default temperatures. What do you think?

thanks and kind regards,
