These patches have been in my tree for a long time...I'm hoping to
get them cleaned up properly and pushed upstream.
I know that the numbers need to change to be consecutive with the
current upstream code.
Aside from that, what sorts of changes are needed? I'll send
as a real git patch when it is closer to right.
Thanks,
Ben
