Yes, the test is based on current master, so including that commit.

Well, that is an interesting question. qemu-system-ppc -M mac99 uses openbios and it crashes while still in the openbios window just when it tries to boot the hd. Besides Mac OS 9.2, I now also tried booting a Mac OS X 10.3 image and it crashes just the same.
