finaly can get framebuffer working on 6970, how: delete ATIRadeonX3000GLDriver.bundle, works on second boot
its possible to backport this feature from Lion to snow leopard, copy these 4 kexts from lion into snow leo: ATIRadeonX3000.kext ATISupport.kext ATIFramebuffer.kext ATI6000Controller.kext and use this aty_init.
Also, there is now Cayman XT, Cayman pro, gl renderer strings inside ATIRadeonX3000GLDriver, but sadly they arent used, 6970 is still unknown cypress gl renderer(if you recover x3000GLDriver, after booting to gui, and launch glview)
bad news: acceleration on 6970 is still borked, gives a lot of gpu debug dumps, so need to disable it by removing GLDriver bundle
for gf100 nvidia cards still need to apply this patch.
