Yes, that I plan to use the virtqueue notification instead of polling.
Can you try patch 1 and 2 from the a patch set, which I posted to LKML. for 
example see
http://linux.derkeiler.com/Mailing-Lists/Kernel/2008-06/msg00997.html

Please tell me, if you cannot get the patches from the archives, I can then 
send them via mail to you.
