Yeah, patches are required that aren't yet in Rusty's queue.  I'll 
update the list once we've gotten his queue straightened out.  The oops 
is most certainly from the use of unsigned int in vring_init instead of 
unsigned long.  I have a patch on 
virtualization@lists.linux-foundation.org for that but I don't think 
Rusty's pulled it in yet.
