Motivation for this change

To prevent this beautiful piece from eventual obsolescence in NixOS.

While it is great for everyone that console drivers in the Linux kernel tend toward a minimal and solid implementation, some of us need full-featured console without a display server. I, as one such person, want to put my hand up now. See fbcon: remove soft scrollback code and fbcon: Disable accelerated scrolling for detailed contexts.
