I must admit, the fb situation is very confusing and the Documentation directory seems to be a mixture of old, new, wrong and just flat out obsolete stuff.

[gentoo-user] scrollback using framebuffer
Hi group, I'm using the nvidia framebuffer(CONFIG_FB_NVIDIA=y) but I can't get scrollback to work for more than a few lines. I've added 'fbcon=scrollback:128' to my kernel line in grub.conf but scrollback is still disabled. Is there some nvidia specific way to do this?
