I bumped into a user in IRC pointing out that tty listing (ls -la /usr/bin) is rather slow on Sabayon. After a 10 seconds google search I bumped in this article here: http://gddd.wordpress.com/2009/10/08/ad/
So I've added the command to /etc/default/grub so it looks like: GRUB_CMDLINE_LINUX_DEFAULT="video=vesafb:ywrap,mtrr:3" regenerated my grub menu: #grub-mkconfig -o /boot/grub/grub.cfg and after a reboot I can confirm this really speeds up tty for me.
