Hello Johannes, as you can see in the picture, q66 is using a 6470.
Coincidentally, I just found a post in the Linux on PowerPC Mac Facebook group from someone who also uses a 5770 on Void Linux. He also had problems. But then changed his xorg file back to the original and it worked. His 5770 was from a MacPro by the way ;-) Christian Zigotzky uses a 6970 in his X5000, IIRC. All Terascale GPUs should work. Also a R5 230. I myself don't have a G5 anymore, unfortunately. So I can only give you limited tips.

Ok, won’t try the X1900 then. I would try further > investigation and debugging (modules, xorg and so) if I knew that card should > work.
