A tested (on amd64 and i386) patch against netbsd-5 can be found at:

http://ftp.netbsd.org/pub/NetBSD/misc/sborrill/netbsd-5.1-xenfront-rx-copy.diff

However, there is a small bug with these patches. If the network that the 
vif is attached to is changed within XenCenter, then it seems to revert to 
flip mode (with all the problems this causes, i.e. killing the XenServer 
dom0 network stack and hanging all VMs). During this operation xennet0 
detaches and reattaches.
