last 100 lines of dmesg when the latest crash happened

>From time to time kwin_x11 crashes. It often happens when I open up the chrome
browser, or konqueror, or both. It sometimes happens at other times. It does
not always happen when I open those applications. This happens on my desktop
and on my 2 different laptops. 

Because this happens on all 3 computers with different drivers, I think this
must be related to something other than the driver. However, for initial
troubleshooting purposes, I will focus on my desktop, as I do not always have
ready access to my laptop.

When kwin crashes, all windows move to my current screen and the header bars
disappear on all windows. The way to recover is as follows. I hit alt-f2, and
type in konsole. This opens a konsole window (without the header bar), I do the
following:

> ps ax | grep kwin

This gives me the process numbers. I kill the kwin_x11 dead process with kill
-9, and the drkonqi process which is initiated (but cannot be used because the
gui window for it doesn't open), I kill drkonqi with kill and the process
number.

Then I can either restart kwin_x11 in that konsole window or by hitting alt-f2.

That is always reproducible to recover without having to kill X. However, it is
still very disruptive to my regular work and happens at least 3 times a day, on
whichever computer I am using at the time.

This last time, I restarted it in that konsole window so that I would be able
to see if there is any feedback while it is running. 

I am attaching 3 files - my Xorg.0.log, a portion of dmesg, and the konsole
output that was given when kwin_x11 was run in that konsole window at the last
time of the crash.

Here also is my hardware info for my graphics card. As I
