Alex and I tried some PLL changes that had different results.

Broken (post-patch):  268/9/3
Fixed (pre-patch):  1072/27/4
Almost working, still occasional flicker:  804/27/3

The 804/27/3 was reached via:

<agd54> try changing line 232 of radeon_crtc.c
<agd5f> change the '<' to '>'

} else if ((flags & RADEON_PLL_PREFER_LOW_REF_DIV) && (ref_div < best_ref_div))
{
