I can confirm this on my PowerBook G4, Radeon 9600 (r300, Edgy). Acceleration worked fine in Dapper. My glxinfo output also reports "direct rendering: Yes".

I can confirm that an iBook G4 with the r200 driver works OK in edgy. -- 3d rendering performance regression Dapper->Edgy with Radeon 9600 M10 https://launchpad.net/bugs/61607 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
