I had similar problems when upgradeing to X4. My guess is that X4
doesn't use the same frequensies that X3 did. Since it doesn't need
(use?) modelines I think there are some "hardcoded" modes built in.
The brutal fix I did was to increase VertRefresh slightly, but like the
config file says, it can break your monitor. I'v puched my monitors far
beyond what the're built for without breaking any though, it just gives
you a totaly useless flickering picture, or flash on and off trying to
set the mode.
If you do increase your settings, (like always) you have been warned!!
Btw, the modelines you included bellow don't include the 1280x1024
resolution, the highest I can find is "1152x864".
If someone knowing the internals of X4 is reading this, please explain
the "missing modeline" issue out for me.)
