After upgrade to Gutsy I am also experiensing this problem :( I am using KDE (without Superkaramba) on Toshiba SA10 laptop (Intel 855 video). I have tried to disable screensaver, ACPI, etc, etc - no result, after some time (~30 min) Xorg freezes, music (Amarok) stops, Xorg is using 100% CPU, but system is available via SSH. Seems it is an Xorg bug...
