On second thought, there is no Gtk/Qt GUI because that is supposed to
be external to Qemu. By the same logic, why should there be any splash
screen? The external GUI can probably show it as easily using the same
Gtk/Qt/whatever. The control channel may still be needed.

Alternatively the BIOS could load the image and fade parameters from a
new ROM or from the configuration device and draw it to screen. This
would need some PNG support to BIOS, or that the image stored in raw
form.
