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.

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. Normally the fan should start to work
if a special temperature threshold is reached.

Here you see the difference between 2.6.21, when it all works correctly, and
2.6.22 and 2.6.23: the screen resolution of the boot screen changed to
the native resolution 1024x768 (in 2.6.21 it still the default terminal
resolution) 

This only means that the kernel's radeon driver has changed.

It's difficult to say what's going wrong.

What's the CPU load when the fan is spinning?

The rest of the systems works fine. I notice no anomaly.

Greetings,
Daniel
