I've done quite a bit of work on Cormac's tree (primarily to fix CUDA
issues that broke OS X among other things) and posted it to the
qemu-devel list at
https://lists.nongnu.org/archive/html/qemu-devel/2015-10/msg05556.html.

The patchset posted works well for me here, and I suspect will fix the
issues that you've been seeing. Note that you'll also need the separate
OpenBIOS binary mentioned in the link above if you want to try booting
OS 9 since one of the OpenBIOS patches hasn't been applied to trunk
since it regresses other images.


ATB,

Mark.
