[OpenBIOS] CUDA has problems with Mac OS 10.4

[Programmingkid]

I built Cormac O'Brien's QEMU repo for Mac OS 9 and tried to boot my Mac OS 10.4 boot cd. Mac OS 10.4's kernel panics because of a CUDA problem. I did use the mac99 target. Here is the error message: 

panic(cpu 0 caller 0x16E786CC): CUDA - TODO CHECK FOR TRANSACTION TYPE AND ERROR

This is the command I used: ./ppc-softmmu/qemu-system-ppc -boot d -cdrom ~/tiger.iso  -prom-env boot-args=-v -usb -M mac99

I think there is still something wrong with CUDA. But we might not have to "fix" it. When we use the mac99 target, the PowerMac3,1 Macintosh system is what we are trying to emulate. My sources indicate that the PowerMac3,1 doesn't have a CUDA chip. This chip is used for ADB communications. Using it only on the BeigeG3 target makes sense. 

My sources for the PowerMac3,1 system is this link: http://www.everymac.com/systems/apple/powermac_g4/specs/powermac_g4_350_agp.html

and this device tree:
