What's the bug?
	- preboot being called too late, or
	- splash_screen_prepare() being called too early

It seems that having splash_screen_prepare() called early
makes sense, because stdout could be set to include VGA
and having access to stdout is very useful in preboot
commands.

Please advise,


Eric
