Subject: [PATCH] vt: disable console blanking by default

  Remove default 10 minute blank interval. Instead: never blank by
  default.
  "Screensaving" is no longer useful.  Today it only provides
  obstacle when interacting with text console, especially through
  remote lights-out management solutions.
