Have you seen this post[1]? What happens if you follow those
instructions (except adding the patch) and see if you can boot the qemu
platform. If that works, which I expect it to, try again with the 2.06
release and see if that works also. I suspect you're not including
needed modules (namely ones for displaying graphics among others).
