I'm not precisely sure where to look. Keep in mind that Debian doesn't have a proper upstream for XFree86 anymore. X.Org is a different, albeit related codebase, and even if The XFree86 Project, Inc. didn't have something other than heaping mounds of scorn for Debian, I'm pretty sure they don't support 4.3.0 anymore. > > I could use some advice as to what the best path forward is, even once I > > have more information from the submitter, so I am tagging this bug "help". > > Ok.

Just within the past two months it's been hacked on by Roland Mainz, Vladimir Dergachev, Alex Deucher, Egbert Eich, Daniel Stone, Michel Dänzer, "kuhn", and Matthieu Herrb. All that activity is great in contrast to XFree86; unfortunately, it leaves me puzzled as to who has ownership of that part of the tree. ;) > 2) make the ati wrapper use only the first function. > > Investigating 2) right now, but i don't promise anything.
