So I think this is a bios bug. Patchset fixing this applied.

So, what's the best way to propagate the fixes upstream?
Avi, Anthony, please advise.

Avi, after applying this, you need to generate a new bios binary.

Anthony, qemu keeps bios binaries in source tree.
I can't post a patch changing these, can I?
Only people with git access can change them.

BTW, can't we keep the sources around the like qemu-kvm does?
It would be best if pc-bios used git, then we would
include a submodule, as it is we can set up a git-cvs
mirror at qemu site, and then include a submodule.
Makes sense?

  pc-bios: enable io/memory unconditionally
  qemu: make cirrus init value pci spec compliant
  qemu: cleanup unused macros in cirrus
