Hi,
Current drivers no longer use atiogl.xml for configuration and so including it (or copying from an older system) won't have any effect. This is not an unintentional omission - current drivers use a different mechanism for recording user preferences and per-application settings. In the thread you link to, the user mentions Radeon HD 4xxx series (which we no longer support with new drivers) and driver version 13.9, which is more than 18 months old. We can only really support and comment on issues related to currently-supported hardware and up-to-date drivers.
If a similar issue is happening for you with recent hardware and up-to-date drivers, let us know and we'll look into it.
Thanks,
Graham
