Bug#649253: eeepc-wmi does not seem to adjust fan speed, but prevents use of fancontrol

Hi Jonathan, 

I will be pleased to answer.

Just to explain: eeepc-wmi will not be fixed, as the developers told me (almost 
2 years ago). The problem of this, is that the old hardware specs of my EEEPC 
1005 HGO are not made available by the vendor. So it is of course impossible, 
to write a kernel module. 

All newer hardware, which is in most newer processors will be supported, of 
course! But as I said, my EEEPC 1005 HGO with the old single core cpu (Intel 
N280), still got the old and undocumentd API.

I am running now linux-image-3.2.0-3-i386 (stock debian kernel of testing).

No, I can choose either to load eeepc-wmi or use the option "acpi_osi="Linux" 
which let me load eeepc-laptop at startup. The second one I call the "old" 
module, as this is the old fancontroller module developed for my old cpu.

If eeepc-laptop is used, then eeepc-wmi will not be loaded.

Of course, I will be pleased to test, but I doubt, that it will work. The 
developers of the modiule "eeepc-wmi" wrote me a mail, where they explained, 
that they will not continue further developing of eeepc-wmi. Not because they 
do not want to, but because they can't - because missing informations of the 
hardware API!

So I changed to eeepc-laptop, which is working fine for me. And for these 
reasons I claimed this bugreport closable.

However, I will test a newer kernel (3.5-X) in the next days, maybe not 
tomorrow, but during the coming week. Response and report will then be sent.

Thank you for your help!
