I tried all 8 pll_flags values, none of them gave me a stable picture. Here are
my notes just copied from the source file:

----
  /* (1) better than nothing, but still 1 flicker every 5-30s */
    //pll_flags = RADEON_PLL_PREFER_LOW_REF_DIV; 

    /* (2) Way better than the first one, the first flicker came
     * about 15 minutes after starting the X server. Then
     * about one per 30-60s. */
    //pll_flags = RADEON_PLL_PREFER_HIGH_REF_DIV;

    /* (3) Flickering starts right away. Similar to Nr. 2 otherwise. 
     * flickers every 15-120s */
    //pll_flags = RADEON_PLL_PREFER_LOW_FB_DIV;

    /* (4) Quite bad, just as without pll_flags being set here.
     * Flickers every 2-15s. */
    //pll_flags = RADEON_PLL_PREFER_HIGH_FB_DIV;

    /* (5) Just as Nr. 3 */
    //pll_flags = RADEON_PLL_PREFER_LOW_POST_DIV;

    /* (6) Similar to Nr. 2 */
    //pll_flags = RADEON_PLL_PREFER_HIGH_POST_DIV;

    /* (7) Worst of all: From time to time, the display OSD even shows
     * an out-of-sync warning. */
    //pll_flags = RADEON_PLL_USE_FRAC_FB_DIV;

    /* (8) Similar to Nr. 3 */
    //pll_flags = RADEON_PLL_PREFER_CLOSEST_LOWER;

Alex, what should I do? I feel the growing urge to buy another graphics card...
Or is there a real chance that the problem can be fixed?
