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

I will test for non-r2 today with these paris.
