Solution:
– install cpufrequtils #sudo apt-get install cpufrequtils
– edit #nano /etc/initrd/cpufrequtils
– change line „ondemand“ to „performance“
– check System #dmesg
– System show „unstable clocksource“ last line
– edit #sudo nano /etc/boot/menu.lst
– add to Kernelparametes line
/vmlinuz-2.6.26-2-686 root=/dev/hda3 ro quiet vga=normal clocksource=acpi_pm

This will run System on max. Speedstep and Videos does’nt hang X-Server.
