RadeonNI-OSX: Radeon HD 7570 Driver for OS X 10.4
Apologies if this breaks any rules.
RadeonNI is a ported driver for the Radeon HD 7570 that works under OS X 10.4.11 Tiger PowerPC. More accurately, it's a patched Mesa + a ported hardware interface from the Linux Kernel + a couple of plugins that enable the usage of Mesa as the GL driver for OS X. Performance is not great, but it's already better than the 6600 LE. You can download it under Github Releases. It can probably be made to work with other TeraScale 2 GPUs, but I only have a 7570 to test with at the moment and as such it is hardcoded to that specific PCI ID.
Full disclosure: The driver is 100% vibeslopped, I am not responsible if your 7570 catches fire or any other personal/bodily harm, works on my machine, etc.
