The ATI dev on twitter made no such claim. In fact he never made any claim about stability at all. Just that the new driver was missing functionality, so only specific things (like Doom3) got it and they were shipping 2 OpenGL drivers as a result during 2004-2007. End-users weren't broken during that timeframe. The old driver didn't suddenly break and get super unstable. If anything the complaint is that the old driver was too stable, it wasn't getting new features & changes fast enough.
