I think the requests get dealt with in batches every couple of months. I
don't think the patch should go in until we get a response, unless we don't
mind all users having to change their /dev/xvc0 node down the road (I
presume they'll need one to run a getty on it from inittab; running on
/dev/console never worked very well for me in the past).
