I don't understand the purpose of this option. There are two
video display endiannesses I can think of:

(1) The guest video device endianness. We should just get this
correct according to the definition of what the hardware does
(and it's not dependent on which host UI we're using)
(2) The host graphics framebuffer endianness. We should
automatically determine this by either asking the host's
GUI about it or by just knowing it if the host is always one
way. (This isn't dependent on what guest is running, either.)

So what is this option doing? It shouldn't be needed for either
(1) or (2)...
