Of the patches it looks like the only one that really has any issues is this one and it is mostly due to the sysfs implementation. The others I would say can be applied and pushed up into the net-next-2.6 tree. We're currently working on an iproute2 based solution for configuring VFs and can incorporate this functionality into it at some point in the future.
