It's certainly an option, and it might well be worth having -- an 80x25
screen only takes 2k or so of RAM, which isn't much on a 16MB machine.
You'd implement it by having the rollback in videoram as it is now, and
just copying the _entire_ video buffer into some other storage when a VC
change happens. This would slow down VC switching a bit, but not much,
and wouldn't have any other bad impacts.
