Sorry for the delay. I have integrated the gatos changes but unfortunately they broke 3D acceleration so I will not put it in 9.1. I will try to get them working after 9.1.
Could we have the driver available with another name (like ati.2 ...) so that we just have to chose it in XF86Config-4 to have Xv on Mach64 or may this still break something ?
