I believe QEMU has handed ownership of this off to coreboot. Which makes sense.

I believe the VGA image will be correct. This might also affect the returned values for some interrupts. This is caused because the set_cursor_position routine fails to save and restore %bx. I'm working on a fix for this. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1670509/+subscriptions
