Comment 28 for bug 278471

Well...I was able to get the Ubuntu Live-CD to flicker the same way as Kubuntu. It doesn't do it at the 7 to 12 second frequency though. Only when you do a certain function and that is:

Control Center --> Hardware --> Screen Resolution.

As soon as I click Screen Resolution, it flickers just like mine is doing under Kubuntu. The only difference is that is stops once the Screen Resolution window appears.
