It looks like you are saying you wish to keep the CUDA device. Mac OS 9 is most likely hard coded to expect via-pmu instead of via-cuda on the mac99 target. Moving on to via-pmu might make QEMU more compatible with Mac OS 9. I will still try your patches. Do you have a repo that I could just clone? It is a lot less error prone than patches.
