I have done so, though to be honest I don't see that panic even if I use
-nographic, QEMU still silently loops for me.

PPC emulation loops on booting a FreeBSD kernel

Status in QEMU: New
Bug description:
Has anyone tried booting FreeBSD8.1-ppc under QEMU (Linux x86_64 host; PPC
guest)? I can get Linux/PPC to run fine, and FreeBSD8.1-i386 as well; but
there seems to be a problem with whatever the FreeBSD8.1 kernel does, that
QEMU's PPC emulation can't handle.
I am using the latest version of QEMU from GIT as of 25/8/10. I don't know how
to get a "git commit hash", so I can't quote it.
The kernel starts OK then loops after "Kernel entry at 0x100100 ...".
The command I am running is
qemu-system-ppc -cdrom FreeBSD-8.1-RELEASE-powerpc-disc1.iso -hda
freebsd8.1-ppc -m 94 -boot d"
I obtained the kernel from
ftp://ftp.freebsd.org/pub/FreeBSD/releases/powerpc/ISO-IMAGES/8.1/FreeBSD-8.1-RELEASE-powerpc-disc1.iso.
