thats bad news... a fix from Apple is not only unlikely, but it would only be on the latest OS, they just don't do graphics updates on older OSes. It seems like it wouldn't be that hard to code in Wine to use the old way hack if its OSX and ATI. Sure the 1.5.1 way fixes issues, but when your frame rate is running 5% to 10% of what it used to, its still unplayable.
