This is why I suggested to test first via radeon.modeset=0. Blacklist means don't load the radeon kernel module, which is what radeon.modeset=0 causes.
I tried radeon.modeset and also did initramfs rebuilds, neither helped though.
But I went on and installed Arch Linux as I commonly use it on my other machines, and after some fiddling with the Apple UEFI, the system worked out of the box by installing mesa and the ati drivers :)
Thanks for your help!
