No, fbcon had some bug too, although I've paged out the details. See
commit 50145474f6ef ("fbcon: remove soft scrollback code").
If I remember correctly (and it's entirely possible that I don't), the
whole "softback_lines" logic had serious problems with resizing the
console (or maybe changing the font size).
There may have been some other bad interaction with
foreground/background consoles too, I forget.
