I asked for help in the ubuntu forums: http://ubuntuforums.org/showthread.php?t=267836
As suggested there, in addition to he options I already added, I put these also into my xorg.conf Option "DRI" "true" Option "ColorTiling" "on" Option "EnablePageFlip" "true" Option "AccelMethod" "EXA"
So my device section looks like that:
Section "Device" Identifier "ATI Technologies, Inc. M24 1P [Radeon Mobility X600]" Driver "radeon" BusID "PCI:1:0:0" Option "NoAccel" "false" Option "AGPMode" "8" Option "AGPFastWrite" "on" Option "DRI" "true" Option "ColorTiling" "on" Option "EnablePageFlip" "true" Option "AccelMethod" "EXA" EndSection
With this config everything works well!
