I did, at one point, a long time ago, get a NV34 G5 PowerMac7,3 working fine with nouveau. I'm curious if something in your VBIOS is different, or if the logic has regressed. (It would have been working in 4.4 or so.) You can find the VBIOS in of, it's called "NVDA,BMP", should be accessible in procfs or sysfs somewhere, but not 100% sure where. (From an old guide, /proc/device-tree/pci@f0000000/NVDA,Parent@10/NVDA,BMP seems to be it, possibly with some local adjustments.)
