You can try this: http://rapidshare.com/files/15366965...00Pro.zip.html

The only thing you must check it up is to check if your DeviceID is added in the info.plist file inside the Atiradeonx2000.kext, in system/library/extensions

The pkg is called HD2900XT_Pro, but works with my HD2600 pro perfectly!

Good luck!
