Fresh install of Kubuntu Karmic RC on old notebook with Intel P4 CPU, frequency scaling does not work on live CD nor on permanent install. There is no sign any scaling is available at all. Scaling works in Hardy on other partition.

Same problem here, I think. Worked in Intrepid.

$ cpufreq-info
CPU 0:
(...)
current policy: frequency should be within 400 MHz and 3.20 GHz.
The governor "performance" may decide which speed to use
within this range.
(...)
CPU 1:
current policy: frequency should be within 400 MHz and 3.20 GHz.
The governor "performance" may decide which speed to use
within this range.
(...)

$ sudo cpufreq-set -c0 -g ondemand
$ sudo cpufreq-set -c1 -g ondemand

cpufreq-info still lists performance as the gov in charge...
No errors, no warnings, just no apparent change of governor.

$ cpufreq-info |grep "available cpu"
available cpufreq governors: conservative, ondemand, userspace, powersave, performance

$ lsmod |grep p4_
p4_clockmod 4164 1

I marked this bug as invalid. I was able to verify with "powertop", that frequency scaling is indeed working on final version of Karmic in my case.
I suggest to report bug described in #2 in a separate bug report. "p4_clockmod" module is not used at all in my case.
