I wish to raise awareness that setting the VertRefresh to 75-117 on a G3 iMac makes it possible for X to drive the CRT at refresh rates that are not supported by the hardware. It appears to run well but a month or so later your CRT is killed by this. I let the magic smoke out of one iMac and I had almost killed a second one when I realized that the refresh rate is probably to blame.
I do not have a good answer as to the right information to put into xorg.conf, but I am %95 certain that 75-117 is not it.
