Please send me your ofctl -p and dmesg output, maybe there's some weirdness in the address ranges reported by OBP. The last few changes I remember were for qemu's tcx emulation, some of that broke it for you ( and who knows if different OBP versions behave - all I had was one )
They're quite large so I didn't put them directly in the message. The dmesg output is at https://pastebin.com/86iX1bpg and the ofctl output is at https://pastebin.com/d3VzzMfC
