Where is it configured 'ondemand'? Change that to 'performance' and you
should have full CPU speed.

Ok, did a little CLI hunting and have some ideas for you.

First, I grepped for 'ondemand' in the /etc directory (I'm on 11.0 so
there might be differences) and came up with the following (among
others):

init.d/haldaemon: *ondemand*)
init.d/haldaemon: modprobe -q cpufreq_ondemand >/dev/null 2>&1
init.d/haldaemon: [ $? != 0 ] && $LOGGER ondemand cpufreq
governor could not be loaded

So, this appears to be kernel modules. That led me to check source:

cd /usr/src/linux
find . -iname 'cpufreq*'

which gives (on my machine and some entries snipped):

../drivers/cpufreq
../drivers/cpufreq/cpufreq_powersave.c
../drivers/cpufreq/cpufreq.c
../drivers/cpufreq/cpufreq_ondemand.c
../drivers/cpufreq/cpufreq_conservative.c
../drivers/cpufreq/cpufreq_performance.c
../drivers/cpufreq/cpufreq_stats.c
../drivers/cpufreq/cpufreq_userspace.c

Digging more into /etc I found /etc/sysconfig/powersave/cpufreq which
appears to be where you can set how you want it to be handled (kernel,
HAL). A comment in that file seems to apply in your case:

# This setting will only be taken into account
# if no other policy manager, such as gnome-power-manager
# or kpowersave, is running

I hope you find this information of some use to you! Good luck! :-)

I often go to YAST -> Software Management and then put some
appropriate words in the "search" box. This usually brings
up a ton of programs, most not installed, but it is easy to
see which ones *are* installed.

A moment with man pages might then solve your problem.

Ah ! In that case I misunderstood your problem.

Have you checked that its not a BIOS setting ? My Laptop
has "Speedstep" in the BIOS.
