I was hoping I'd get a chance to submit some QEMU patches for this
before the soft-freeze, but unfortunately I have not been able to.
Since I don't want to hold up features, I remove my earlier objection
and I'm okay with committing this to SeaBIOS.

Hu Tao - if the QEMU part of the pvpanic series is committed to QEMU
I'll commit the corresponding SeaBIOS parts.

Apologies for the delay.
