After a day trying again, the PC locks up again with black screen before login like Timothy wrote.
I tried booting with the i915.modset=0 kernel parameter and the system went through the login screnn, even from the live cd. The only strange thing ist that the boot process stats "Unknown boot option 'i915.modset=0': ignoring" ???
But as I mentioned before, the system performance is eaten up by the Xorg server process with appr. 15%-90%.
Also there is another process called "sreadahead" with takes up the rest of the CPU usage with disappears after a certain amount of time (minutes) after starting the live CD/ installed system.
