Agreed.

We need a framebuffer terminal.  It should be possible to pass a
argument to it which framebuffer it uses.  Some systems have multiple
framebuffers, or multiple ways to access the same video hardware (for
example VGA, ATI and OF, those can be all used to access the same
hardware).

Can you explain this?  You mean we need an object for this?

What makes 64 bits archs special?
