XVidMode extension might be useful to non hardware servers as well (e.g. Xwayand) so that applications that rely on it (e.g. lot of older games) can at least have read access to XVidMode. But the implementation is very XFree86 centric, so the idea is to add a bunch of vfunc that other non-XFree86 servers can hook up into to provide a similar functionality.
