Athlon XP 2000+ cpu freq scaling

Hi!

I have an Athlon XP2000+ and I want to make it possible to lower the freq in software.

I installed the 2.4.22 kernel with ac4 patch and enabled:

[*] CPU Frequency scaling
[*] CPU frequency table helpers
--- CPUFreq governors
[*] "userspace" for userspace frequency scaling
--- CPUFreq processor drivers
<*> AMD Mobile Athlon/Duron K7 PowerNow!

The kernel boots fine but when I do:

# cat /proc/cpufreq 
   minimum CPU frequency  -  maximum CPU frequency  -  policy

Shouldn't say some frequencys like?

minimum CPU frequency - maximum CPU frequency - policy
CPU 0 500000 kHz ( 41 %) - 1200000 kHz (100 %) - performance

Info about my cpu:

# cat /proc/cpuinfo 
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 6
model           : 8

bogomips        : 2968.78

(Currently it's under clocked but I have tested with it at 2000+ mode)

Have I missed something in the kernel?

Please help.

Could you please give output from x86info at www.codemonkey.org.uk x86info --pm

A dmesg may help as well.

Cheers,
