I installed openSUSE 11.0 with KDE 4.0 and then upgraded it to KDE
4.1.67 (including kwin KDE window manager).
Now during KDE loading I see that login splash screen is shifted and then it suddenly blinks and displays picture like this:
The system hangs completely, I can't switch to ctrl+alt+f# terminal nor do ctrl+alt+bksp.
I have intel 915GM/GMS/910GML graphics card, upgrading Xorg from 7.3 to 7.4 didn't help.
I solved problem by running failsafe session and turning off kwin compositing.
kdm.log contains this backtrace:

I hope that backtrace will give you a hint.
P.S. I also run this software configuration (openSUSE 11.0 + KDE 4.1.67 + XOrg 7.3) on my other notebook - acer aspire one, and it freezes in the same way but only after I used it for some time and/or try to open too many applications. AND it still alows me ctrl+alt+bksp
Please attach Xorg.0.log, according to http://intellinuxgraphics.org/how_to_report_bug.html.

I attached logs for a similar symptoms (a bit different backtrace).
XOrg.log for the inital crash (on my older notebook - dell inspiron 1300) is coming soon
some error information in your Xorg.0.conf,
(EE) intel(0): Mode 1280x1024 does not fit virtual size 1024x1024 - internal error
Could you attach your xorg.conf?
