Let me ask a dumb question:

Why does scrollback rely on video memory? It's horribly limiting.

I'd love to have (or be able to configure) scrollback to come from kernel
memory instead. That way I could choose to have a 1MB scrollback buffer
if I wanted... And it would be 1MB of actual *text*, even in the case of
a graphical console.

Has anyone else considered something like this? Are there technical
reasons for not doing so?

Curious,

Jeff
