Now, all this comes into play only with the qemu provided by kvm releases since the savannah one doesn't have the code that uses TUNSETOFFLOAD, IFF_VNET_HDR etc.

Modern distros have this sewn up correctly.  For example my desktop runs 
kernel-2.6.27.21-170.2.56.fc10.x86_64, and has matching headers from 
kernel-headers-2.6.27.21-170.2.56.fc10.x86_64.
