AMILO pa 3553 acpi problem

Hi!

I've recently switched from Ubuntu to Arch and been tinkering. After getting a (barebone) graphics environment up I began running into problems. My laptop (Fujitsu Siemens AMILO pa 3553) began overheating badly and the fan, while on, didn't increase or decrease in speed. Just humming away at a leisurely and insufficient pace.
So I thought I would fix the problem by forcing the fan speed, which is where I realized my /proc/acpi/fan was missing! It was there when I used Ubuntu and just to make sure I wasn't misremembering I rechecked the specs of my laptop on the internet. It _should_ be acpi compliant.
I've tried running sensors-detect (which assure me that k10temp is correct and loaded and all I need) and no matter what I do, it simply doesn't seem to register anything else than the temperature of my (2) cpus and my AC adapter.

I'm out of ideas. You guys have any?

Did you already look into this Wiki article about fan speed control?

Yes, yes I did.

As far as I can read the wiki assumes that the OS acknowledges the existence of the fan. I have no problem manually configuring a fan, the problem is when for some reason it won't detect the ACPI for the fan. It worked under Ubuntu and I can read on the internet that my laptop is ACPI compliant, so I know it should be possible for Arch to do this.
