No reason at all, in fact that's what I intend to push for. Hopefully
this would be done right now so there is plenty of time till next
release to move around components. The main GATOS CVS branch is quite
stable. As for memory controller I'll either e-mail a separate patch to
Jens Owens, or it will go into the main XFree tree together with the rest
of GATOS patch.
Regardless of the way it is merged the driver major version will need to
be bumped. GATOS drivers does this but only minor - as I did not want to
upload a mesa radeon driver just because of the version change.
