Hi there,

at first great respect for your fast answers. 
I don't think, that the binary ati driver is the problem, because:
1. with switched of "ati radeon display support" in the kernel, the fan
control works correctly (and i still using the ati-driver)

How do you know, however, that the "ati radeon display support" in the kernel
does not interfere with the ATI driver in a destructive way?

I think, but im not sure, that the ati driver is loaded, if X was
started. But at this moment X was not started.

Well, the kernel module part is probably loaded earlier.

2. the fan starts spinning at the boot screen even if the radeon display
driver was loaded (and the ati driver is not just loaded yet).

I'm not sure what you mean exactly.  Can you clarify, please?dann

Well, i see it looks a little bit confused what i wrote. What i mean is,
that the fan at this time starts to rotate, when the "radeon display
support" is loaded at boot time.

I see.

Can you please check:
- What happens if you don't use the ATI driver at all (please unload its kernel
  module before loading the kernel's radeon one)?
- Does the loading of the radeon module trigger the fan automatically?
- What happens if the fan module is not loaded at that time?
