This topic was discussed about a week ago on this list.
The following will reduce the issue to the point where KDE
is tolerable.

Check /proc/cpuinfo and verify your mhz of your proccessor.
If it shows that you are running something like 75mhz then
get Thomas Hood's tpctl utility (on sourceforge.net)
Do the old ./configure, make, make install.

Then add the following to your modules.conf:

keep
path[thinkpad]=/lib/modules/`uname -r`/thinkpad
options thinkpad enable_smapi=1 enable_superio=1 enable_rtcmosram=1
enable_thinkpadpm=1
alias char-major-10-170 thinkpad
below thinkpadpm thinkpad
below superio thinkpad
below smapi thinkpad
below rtcmosram thinkpad

Now do a depmod -a and reboot.

As root type: tpctl --pm-mode-AC=high

This should get you back to your cpu's top speed (i.e, 266,300,366, or 400 mhz)
depending on your model.

Before I did this, I could not run KDE for more than a few minutes before the
desktop would freeze up.  Usually this would occur during a focus change,
tooltip popup, or a scroll bar adjust.

After having do this, I only see it ocasionally (2-3 times a week) when I am in
the
file manager, sliding the scroll bar on the sidebar tree control.

I am not convinced yet that it is a KDE bug.  I think it may be some other
power managemnet setting of the ThinkPad that is causing this.  The problem
is that there are so many settings and the problem occurs so infrequently now
that it will take me some time to find out the solution.

Hope this helps
Dean
