  > With the new 2.6.32 kernel in Squeeze, KMS is turned on. KMS attempts to autodetect a monitor, and if it doesn't find one video goes blank. The way around this is to override KMS with the video= boot parameter.
  >
  > So I modified /etc/default/grub and changed the boot options from "quiet" to "quiet video=VGA-1:e"
