I really doubt it is an endianness problem as the current CVS works
perfectly on GNU/Linux powerpc. The code in op_helper.c adds support for
target little endian access (sparc is big endian), but it is anyway not
used in openbios. We have to debug the problem and find what is wrong
with OS X:

- Which version of GCC are you using?
- Could you please try to run qemu with -nographic?
- Also could you please try to run qemu with -d in_asm,op and send us
/tmp/qemu.log?
