Xorg Log with 1080p screen - fract fb div enabled

This log is with on a 1080p screen with the factional fb div enabled, but
without the second change, and produces a flicker or sometimes just random
pixel corruption (similar to the snow effect pictured in bug #21553), hence the
need for selecting the closest PLL value below the desired frequency.
