What exactly is missing in OpenBIOS. I am currently studying the IEEE
1275 document (OpenBIOS specifications). I would like to add this
system if I can.

OpenBIOS is missing an implementation for local variables. See this

A while back I know someone was working on PPC Support in Qemu to be able to
run Mac OS9-Mac OS X in Qemu on X86 PC's not sure about M68K support though
so is anybody still working on M68K support or PPC Support and how far is it
from being included in a stable Qemu release,I notice Power PC Support still
says Testing on the status page how far is it from being complete?
Thanks In Advance For Replying

M68k with non-colfire targets is pretty much non-existing. At least when it comes to system emulation (which is the one you're interested in).
As for PPC, the CPU and device emulation code should work fine for OSX up to 10.2 or 10.3. Then Apple dropped support for the G3 Beige.
The major bit missing to get those to work is OpenBIOS. It's missing some Forth extension that the OSX bootloader uses, so it fails to load the kernel and boot.
