Thank you Florian.
I just upgraded for 3.2.1 kernel. I have enabled few modules:

Under drivers/hwmon:
    acpi_power_meter.ko
    asb100.ko
    asus_atk0110.ko
    atxp1.ko
    coretemp.ko
    hwmon-vid.ko

Under drivers/acpi:
    ac.ko
    battery.ko
    button.ko
    container.ko
    fan.ko
    processor.ko
    thermal.ko
    video.ko


I loaded them all for now, and still /proc/acpi/fan is not there. sensor-detect generated the following file (comments removed):

============================================================
# Load modules at startup
LOADMODULES=yes

# Initialize sensors at startup
INITSENSORS=yes

HWMON_MODULES="coretemp"

# You should use BUS_MODULES and HWMON_MODULES instead if possible.

MODULE_0=coretemp
============================================================

As you can see, coretemp is loaded.
I read on some forums that you can manually control the fan speed.

I will start some extensive process, to see if the fan will kick.
