Yup, that indeed was the problem. I have another question though: the 
speedfreq daemon that can change the setting according to the load does not 
work with the 2.4 implementation since it uses sysfs which is only present in 
the newer 2.5+ kernels.

Now; I've got this nice cpu, i got it recognized... how the hell do I change 
the frequency?? I'm looking on the net; but I'm not able to find any relevant 
documentation...

Thanks!
