2.4.x kernel and speed-stepping?


Hi,

I'm running MDK 9.2 (2.4.22 kernel) on my IBM R40 Centrino laptop. Just wondering if I can do speed-stepping with this kernel? modprobe speedstep_centrino failed. But I get the following ouput when I do cat /proc/cpufreq and /proc/cpuinfo


[root@205-87 proc]# cat cpufreq
minimum CPU frequency - maximum CPU frequency - policy
CPU 0 600000 kHz ( 46 %) - 1300000 kHz (100 %) - performance

[root@205-87 proc]# cat cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 9
model name : Intel(R) Pentium(R) M processor 1300MHz
stepping : 5
cpu MHz : 1295.832
cache size : 0 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe tm2 est
bogomips : 2588.67


Does this mean my processor is being speedstepped already? But, my battery performance is still 50% (2.5 hrs) of what Win XP (4.5+ hrs) used to offer previously. If not its being speedstepped already, what should I do? I read about using cpufreqd and other daemons like nopowerond, etc. What are they for?

I cannot use 2.6.x bcos of installation problems with my university's vpn client.

No matter what nifty little features and battery life your trying to get out of it... just, upgrade the kernel first? That's always a good step...
