Not obvious. Adrian is working with my m68k branch of qemu (qemu-m68k).
Pure qemu supports only coldfire, if you want to test it, you can't use
debian. There is a coldfire image at http://wiki.qemu.org/Testing, but
of course, it doesn't use the syscalls added by these patches.

I'm currently working to be able to merge my m68k branch into mainstream
qemu. A first series of patch will be available in the few coming days.
