Used to change resolutions for full-screen game playing.

It is not a standard X server. It also did not come from XFree 3.x.

That is correct.

In XFree86, it's something that XFree86 has provided in addition to the
regular X server functions. They let you do all kinds of things. 3D, gamma
changing, screen blanking...

Are you sure that it is the modelines which are the problem? Maybe X just
won't work with it. Standard modelines are supposed to work with all normal
video cards.

Can you get a regular X server to ask the graphics card what dot clock rates
it supports? (I don't remember what option to use)

You are probably correct.
