Your work surely sounds interesting. However, making OpenBIOS boot  
from the disks is not everything there is to it. Alexander Graf had  
once posted a series of patches for making Mac OS X boot in QEMU,  
including changes/additions to device emulation. They were not merged,  
not sure about the status today.

One issue iirc was that you need to obtain some Apple ID from a real  
Mac of yours and pass that to QEMU for it to work.
