It’s only for Lion.
1) get 10.7.2 11C48 beta (from imzdl.com for example)
2) Install all ati kexts from update with pacifist (or install whole update)
3) download this file – removed and copy it to this folder – /System/Library/Extensions/ATIRadeonX3000GLDriver.bundle/Contents/MacOS/
4) install aty_init if you dont want dvd payer/steam/etc to crash (not for macpro). – removed
there is still few small glitches (MSAA crashes driver, opencl doesnt work) here and there.
if it stops at gray screen, reset computer, happens sometimes.
