Thanks for the reminder.... in fact I posted a qemu patch in February
http://lists.gnu.org/archive/html/qemu-devel/2014-02/msg00319.html
I thought it was applied, but it's not yet in trunk....

I used to use a patched qemu, but when I upgraded to 2.0 I forgot
about this patch.
I am going to re-check with a patched qemu, and ping them.
