unsupported CPU with Enhanced SpeedStep

Hi,

I send you some informations about my cpu and cpufreq not working with speedstep-centrino ( deprecated in kernel 2.6.21 ) and not working with acpi-cpufreq

Actual kernel : 2.6.21-2

/proc/cpufino:

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Pentium(R) M processor 1.86GHz
stepping : 8
cpu MHz : 800.018
cache size : 2048 KB
fdiv_bug : no
hlt_bug : no

coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2

bogomips : 1602.01
clflush size : 64

With cpufreq.debug=2 i got this when i try to load acpi-cpufreq module:

kernel: cpufreq-core: trying to register driver acpi-cpufreq
kernel: cpufreq-core: adding CPU 0
kernel: cpufreq-core: initialization failed
kernel: cpufreq-core: no CPU initialized for driver acpi-cpufreq

Tell me if you need more informations .
