Just thought I'd put my two cents in to this discussion, I'm not really 
planning on contributing code to Grub 2, though I might help stimulate 
discussion...

If you wanted to enable both serial and graphical terminals (or any 
other kind(s) of terminals, just that there are more than one enabled at 
once), you'd really have to switch to using the Model/View/Controller 
architecture for user interaction.

However there is also the difficulty that when you have two separate 
terminals into the same session (or whatever else you want to think of), 
that might become a security issue.

Just my two cents on this matter.

Hope this helps (though it might not),
Daryl Van Humbeck.
