We could use a redesign of the console system. Things I'd like to see:

- separation between generic console stuff and low-level (VGA) stuff
- scrollback on all VCs, using a decent implementation (i.e. not depending
on VGA features, since they're of no use to me)

The way GGI does it (using the `scroller' interface) could be a start (but GGI
isn't perfect neither, for machines without a hardware text mode).

If you want to know more about the machines without VGA text mode, please let
me know.
