The maximum PixClk for Sumsung 204b is 162MHz. I > was trying to play with the video= kernel parameter but there is > no way to force the PixClk. Are you saying that forcing a low-refresh-rate mode via video= kernel argument does not help? But you still do get a good picture on the framebuffer console, do you not? In that case, X is overriding what kernel thinks is the best mode, so you should clean up the X config. If wiping the X config does not help, post kernel and X logs.
