Hallo!

I've purchased an Acer TM290, installed sid, downloade and installed vanilla 
kernel 2.4.22 and 2.4.22-ac1 patch (containing cpufreq support for centrino), 
and...

...theoretically I can switch among the following cpu speeds:
- -----
root@quinipt:/# cat /proc/acpi/processor/CPU0/performance
state count:             5
active state:            P0
states:
   *P0:                  1300 MHz, 22000 mW, 100 uS
    P1:                  1200 MHz, 20000 mW, 100 uS
    P2:                  1000 MHz, 15000 mW, 100 uS
    P3:                  800 MHz, 10500 mW, 100 uS
    P4:                  600 MHz, 6000 mW, 100 uS
- -----

But running
echo 4 > /proc/acpi/processor/CPU0/performance

nor using 1, 2 or 3 changes the cpu's speed  8-?

I've had a look at tuxmobil.org but haven't found any answer to my problem.

Thanks!!  ;)

PD  thanks to all who answered my last question about battery time & 
centrino  ;)
