ATI's download page for the current version:
still doesn't support --buildpackage Ubuntu/9.10, so had to use Ubuntu/karmic. So probably not fully working for the final release of Karmic, still.
Haven't rebooted yet, but I'm hoping it will fix opengl for 64bit programs.
Nope, still broken on AMD64 Ubuntu 9.10.
Does ATI have a bug tracker? I assumed they already knew about this with 9.10, and would fix it for 9.11.
