Radeon 6970 still doesn’t work.
However there are some little changes, using Duckweed (not Gibba) framebuffer now solves freeze at white screen at boot, mouse pointer appears, however further we have ASIC hang and gpu stops working normally.
With Gibba framebuffer, gui just freezes at white screen and if you do ioreg -l via ssh, output will freeze at ATIRadeonX3000, so it doesn’t even get to the point where ASIC hangs.
However it’s solvable if you remove ATIRadeonX3000GLDriver.bundle, but we don’t want to miss hardware acceleration.
