Thanks. Here's the (most likely) problem: the -jl kernel patch misses a
critical update to the speedstep-centrino module which is necessary to get
it loaded. Either get the latest cpufreq CVS sources from
http://cvs.arm.linux.org.uk [check for the latest LINUX_2_4 nightly build] and 
replace -jl9's arch/i386/kernel/speedstep-centrino.c with the version in the linux_2_4
CVS, or contact the -jl maintainer to do the update and release a new -jl
kernel.

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!

echo -n "0%0%100%userspace" > /proc/cpufreq

to enable the userspace governor, and then you can set the frequency in

/proc/sys/cpu/0/speed

The last one on ftp://ftp.linux.org.uk/pub/linux/cpufreq/ dates from Aug 
15th. Something wrong there?

Oh, great. Mozilla's caching or the proxy here is not so smart...

Sorry for the trouble...
