One complication is that alot of us are not necessarily testing the
SeaBIOS that is in QEMU GIT. Fedora rawhide includes qemu-kvm.git
snapshots which are updated fairly frequently, but we don't use
the SeaBIOS QEMU includes. Instead Fedora includes the latest
SeaBIOS upstream release.
So Fedora 16/rawhide users would never have seen this particular
bug for longer than a couple of weeks until the fixed SeaBIOS
