Looking at the forum post, it appears to be using:

  *Mode "1280x1024": 108.0 MHz, 64.0 kHz, 60.0 Hz
  Modeline "1280x1024" 108.00 1280 1328 1500 1688 1024
1025 1028 1066

which matches the suggested "Future mode" that the monitor is providing.

I notice also that DRI (direct rendering for 3D) only works in 16-bit. Does setting the depth to '32' also make it work?

I think the vertical lines might be resolvable by adjusting the horizontal-scale and phase (these should be menu options on the monitor).

Does it still occur with a CRT (a none flat-panel); as the lines maybe the result of going Digital->Analogue->Digital and having the match analogue pixels back up to a square grid of pixels.

Those vertical lines are occuring every 100 pixels, so it maybe the case of fitting 99 pixels in 100 pixels width - every 100'th you need to miss one out.

Try reducing the width (scaling) slightly.
