      Did you try recent kernels? I have a G4 MDD and a G5 running with Radeon 9600/9800 cards. Even current 5.1.x or 5.0.x kernels work fine (or even better?) with KMS. On some card<->machine combinations the GPU locks up and resets when reaching the desktop. In this case you can use the kernel boot parameter "radeon.agpmode=-1" as workaround.

        Great! I have a X1950 XT (flashed) ready to install on my Power Mac G5 (just waiting for the power cable to arrive), so it's nice to know KMS is working. Fortunately my G5 is all PCIe, so I don't have to worry about buggy AGP bridges.

          True. But in this case you have to worry about issues Mac-flashed cards (originally being PC-BIOS) can have.

            Well, I tried it a couple of weeks ago, and the system came up. Just a black screen with a white ATi logo and a graphics card, with a flashing red power cable. I guess the BIOS (Open Firmware) Forth code correctly initialised the card, but it won't let the system boot without the power cable. 😉
