Does using either of these in conjunction with the others help?
RADEON_PLL_USE_FRAC_FB_DIV
RADEON_PLL_PREFER_CLOSEST_LOWER

E.g.,
pll_flags = RADEON_PLL_PREFER_LOW_REF_DIV | RADEON_PLL_USE_FRAC_FB_DIV;
or,
pll_flags = RADEON_PLL_PREFER_LOW_REF_DIV | RADEON_PLL_USE_FRAC_FB_DIV | RADEON_PLL_PREFER_CLOSEST_LOWER;
etc.
