At last someone who sees where I'm coming from.  X will never be 
flawless for the simple reason that it is dependent on video hardware 
and I know for a fact that video hardware is often flawed.  If I use 
the settings listed in my monitors documentation to set up XF86Config 
it just won't work.  Why ?  Because the documentation is WRONG.
I have seen monitors with 1024*768@75Mhz printed in bold text on the 
box that choke at anything frequency above 72MHz at that resolution.
I have sean video cards that work well if you tell X that it is 
something else.
