Jin gave me his new patch set. I tested it on R2.
All of the bellow work well.
(HOST) (qemu-system) (Debian ISO)
64eb -> i386 -> i386
64eb -> x86_64 -> i386
64eb -> x86_64 -> amd64
n32eb -> i386 -> i386
n32eb -> x86_64 -> i386
n32eb -> x86_64 -> amd64
32eb -> i386 -> i386
32eb -> x86_64 -> i386
32eb -> x86_64 -> amd64
