Yes, but in the past time we have a lot of work in Tizen project, so I
delayed this work a bit. If anybody wants I can send latest patches to
let you continue the work or maybe improve since I'm not sure if I'll
have a time to continue until 15'th of june (but I'll try . Actually
my work is based on Peter's virtio-mmio patch set 
http://lists.gnu.org/archive/html/qemu-devel/2011-11/msg01870.html, so 
maybe it's worth
adding him in the list <address@hidden>.
