Fan control is definitely broken still.

Right now the machine says:

ber@mel-mobil:~> cat /proc/acpi/thermal_zone/TZ*/temperature
temperature: 70 C
temperature: 58 C
temperature: 30 C
status: off
status: off
status: off
status: off
ber@mel-mobil:~> acpi -V
Battery 1: charged, 100%
Thermal 1: active[1], 70.0 degrees C
Thermal 2: ok, 58.0 degrees C
Thermal 3: ok, 30.0 degrees C
AC Adapter 1: on-line

An the fan(s) is not physically active.

It seems to me that once a fan state is set to "off", it cannot be turned back
on again.

I also found this in dmesg:

ACPI: Transitioning device [C352] to D0
ACPI: Transitioning device [C352] to D0
ACPI: Unable to turn cooling device [c17e69b4] 'on'

Are there any useful APCI debug options in the kernel that I could enable to
get more info?
