One problem of initializing it is that hardware will be accessed,
while it might not be desirable.
Maybe we could move this to grub_term.init ?  This way hardware is not
accessed untill user requests a switch.

This is the same way it works with gfxterm. You define video mode
beforehand of the switch.

But there is actually a one architectual issue here... How are we going
to support graphical terminal and serial terminal at the same time? eg.
allow user to enable multiple terminals...

Grub-devel mailing list
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),
