No tty[1-6] in Ubuntu 7.10

If you notice that you don't have any tty's and no boot prompt (when the Ubuntu splashscreen is not enabled), then this might fix your problem.

fbcon
vesafb
# blacklist vesafb

The -u option is used to update your existing initrd image. Please make sure that you first edit the initramfs modules and the blacklist before you update the initramfs.
