Re: Unable to turn fan on - Asus M3N - 2.6.0-test9bk4

[Lindsey Simon <lsimon-kAMMLXQ8Af9Wk0Htik3J/w@public.gmane.org>]

My FN00/state's change from on to off as well, but the fan doesn't actually
turn on when the state says it's on.

Do you insmod the fan module or not? I do, but maybe I shouldn't?

Which of the ACPI modules do you turn on and which do you not?

Maybe that's the ticket?
