Are you saying the xserver makes a difference?  One thing you might
try is choosing a different mode if several variations are available
for your monitor.  A lot of DVI monitors are pretty picky about the
timings they like.  if you post your xorg log I'll take a look.  If
you see differences between 6.8.191 and 6.8.192/6.9.0 let me know, as
I made some changes to the pll code.
