Are you saying it's working ok now?

Which log is which?  Does one version of the driver work better than
the other?  You'll notice they are each using different pll dividers:
Xorg.0.log is using:
freq: 108000000
best_freq: 108000000
best_feedback_div: 96
best_ref_div: 12
best_post_div: 2

while Xorg.1.log is using:
freq: 108000000
best_freq: 108000000
best_feedback_div: 16
best_ref_div: 2
best_post_div: 2
