Before we did submodules and had a responsive BIOS maintainer, we maintained 
patches within qemu.git for our external dependencies.  I think that's a good 
strategy here too.  It's a little painful, but not entirely awful.

At least it makes it possible for you to (hopefully) trivial rebase a patch if 
something is still in limbo.
