In theory, we can put a bootsplash_disable() call automatically when
the certain level of kernel message appears, too. It's a question
whether such behavior should be dynamically configurable or not,
though.

BTW, one thing that is bad with quiet boot option is that it hides
always messages and shows only errors. With this bootsplash scenario,
you can boot without quiet option. Once when the splash turned off
(either by user action like key input or by some kernel trigger),
you'll see the whole messages, thus have far more information there.


thanks,
