console/tty (framebuffer?) too slow!!!

if you do

ls -al /usr/bin

in tty/console (ctrl+alt+f1), you may found its scrolling is very slow or/and lag, so i found a way to frameskip:)
just add

video=vesafb:ywrap,mtrr:3

to /boot/grub/menu.lst ‘s kernel line, so after added, mine look like:


title Arch Linux
root (hd0,2)
kernel /boot/vmlinuz26 root=/dev/sda3 ro usbcore.autosuspend=1 vga=0x361 video=vesafb:ywrap,mtrr:3
initrd /boot/kernel26.img

now reboot and enjoy fast scrolling!
