These are the results of my bisection:

Has anyone recently been successful booting on ppc, could this be some endianness issue? It works fine on OpenSolaris/amd64 host.
It also works on OpenBSD/Sparc64 host, which is big endian. Linux/i386 works too, so 32 bit case is covered.
I doubt that this can be a problem in OpenBIOS, I find QEMU more likely suspect. Can you boot any other big endian targets on PPC, for example PPC?
Yes, ppc-softmmu boots Debian CD fine.
However, ppc64-softmmu booting Debian CD segfaults immediately.
sparc64-softmmu booting Solaris 10 U3 DVD immediately crashes with the following output:
