I think you should be loading radeonfb, but I don't see it mentioned in your dmesg output. Also see https://wiki.debian.org/DeviceDatabase/PCI?highlight=(9600) . I can't help with the G3 problem, but here's what I found with a G5... I found the easiest path was to replace the stock NVIDIA GeForce FX 5200 card with a Radeon 1900 card on my G5. I was not able to get Debian to work with the NVIDIA card on the G5. I seem to recall Apple used a special Radeon 1900, and not a standard one. I bought the Apple compatible Radeon X1900 GT from eBay. Here are the drivers loaded for my G5, in case it helps. $ grep -i -E 'radeon|video|drm|display|gpu' /proc/modules amdgpu 9374033 0 - Live 0x0000000000000000 radeon 2298068 3 - Live 0x0000000000000000 drm_buddy 11845 1 amdgpu, Live 0x0000000000000000 gpu_sched 41023 1 amdgpu, Live 0x0000000000000000 i2c_algo_bit 9361 2 amdgpu,radeon, Live 0x0000000000000000 drm_display_helper 147756 2 amdgpu,radeon, Live 0x0000000000000000 drm_ttm_helper 4100 2 amdgpu,radeon, Live 0x0000000000000000 ttm 83004 3 amdgpu,radeon,drm_ttm_helper, Live 0x0000000000000000 drm_kms_helper 181723 3 amdgpu,radeon,drm_display_helper, Live 0x0000000000000000 drm 567853 11 amdgpu,radeon,drm_buddy,gpu_sched,drm_display_helper,drm_ttm_helper,ttm,drm_kms_helper, Live 0x0000000000000000 drm_panel_orientation_quirks 1620 1 drm, Live 0x0000000000000000 Jeff
