Hi all!

I just upgraded to SuSE 9.1 yesterday, and I'm rather content with what
the guys at Novell/SuSE have done!

I do have one problem though: the CPU fan (in my HP pavilion ze4360) is
running all the time, due to the fact, that CPU scaling does not seem to
work. At least I assume that.

Starting cpufreqd does not work, it returns the following error message:

Error: Could not open file for writing:
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Error: No such file or directory

The appropriate kernel modules all seem to be there:
holger@hppavilion:~> lsmod | grep powernow
powernow_k7 5664 0
freq_table 4612 1 powernow_k77

And dmesg tells me:
holger@hppavilion:~> dmesg | grep powernow
powernow-k8: AMD Athlon 64 or AMD Opteron processor required
powernow: PowerNOW! Technology present. Can scale: frequency and voltage.
powernow: Found PSB header at c00f18c0
powernow: Table version: 0x12
powernow: Flags: 0x0 (Mobile voltage regulator)
powernow: Settling Time: 100 microseconds.
powernow: Has 14 PST tables. (Only dumping ones relevant to this CPU).
powernow: No PST tables match this cpuid (0x7a0)
powernow: This is indicative of a broken BIOS.
powernow: See

Now, does anybody have an idea how I could convince my little notebook
_not_ to run @ 1.8GHz all the time?

TiA!
Holger
