Comment (by JordanCrouse):

 This is really two individual bugs - 1) how to keep the screen from
 flickering during boot, and 2) what to display and what not to display
 during boot.  Mitch proposed a solution to solve 2), but he really ended
 up solving 1).  It is trivial for us to not display kernel output during
 boot - just remove console=tty0 on the command line and disable
 CONFIG_LOGO in the kernel config - leaving us with a black screen until
 userspace comes along.  Filling that black screen is important, but not
 really the scope of this bug.

 Mitch's solution perfectly fixes our problem with flicker - freezing the
 DCON until the kfb has loaded (and possibly also freezing it again while X
 loads) is the best way to ensure a flicker free experience.  What we
 actually end up displaying in OFW, in the kernel, and in X is a question
 of some debate - and probably better suited to the artistic and political
 types as to what they want to see and experience.  All we can do is make
 the experience technically sound, and freezing the DCON is the perfect way
 to do that.  I vote we do it.
