2.4.x kernel and speed-stepping?
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

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.
