Same problem here. I disabled DDC for a try: the flickering persisted and Xorg logged on every flicker a message of DDC not being enabled. When starting X with the monitor attached, the bug appears after the login (not in KDM). I suppose this bug is somewhere in KDE but occurs only in conjunction with the intel driver.
