I test the patch and no line solved the problem. I see the worst result with:
pll_flags |= RADEON_PLL_PREFER_LOW_FB_DIV;

In a second run I vary the modelines, but only the values in X,Y and polarity.

Modeline "NAME" X 1920 1968 2000 2080  1200 1203 1209 Y -hsync +vsync

I could reduce the blanking, but not solve the problem. 

Does it makes sense to vary the other values?
