Well, I have to admit that in a sense, this patch set is not
particularly useful if it does not implement at least one driver.

The gfx device I'm currently working on doesn't use the DISPI
interface and is pretty experimental for now and I guess the emulation
code would have to be accepted first in Qemu before I can submit the
driver in seabios, which could take some significant time.

I could have a look and see how much work remains to have a complete
DISPI VBE driver, but it was not initially in my plans to be honest.
Maybe the RedHat people would me more interested by this project,
since they need it for QXL.

Also, I implemented this vbe driver skeleton with an interface which
could be as generic as possible to allow to implement several
different drivers. But I am actually wondering now what would be the
best way for several drivers to share the same interface in terms of
