  Log:
  Remove the DPMS code in creator_blank_display(), as it causes some
  LCDs to blink in the V_DISPLAY_ON case, at least in combination with
  some 13W3-VGA-adaptors (what's exactly going on is unclear though,
  as it happens when all of H-sync, V-sync and video output are enabled
  and not touching the sync bits from the preset fixes it). Thus
  creator_blank_display() now is reduced to turning the video output
  on/off.
  Although that DPMS code did what the XFree86/Xorg sunffb(4x) does,
  it was questionable in the first place, as both implementations
  also turn(ed) off the video output on standby and suspend, thus most
  likely causing the monitor to turn off instead of entering standby
  or suspend as intended (at least my monitors don't).
