lcd driver provides support for the front panel LCD
  display found on newer HP PA-RISC workstations and servers. This LCD can be
  made to show a heartbeat based on the load average by setting the
  sysctl(3) variable
  machdep.lcd_blink to a non-zero value.
lcd driver first appeared in
  OpenBSD 4.2. It was ported to NetBSD
  6.0 by Adam Hoka and Nick
  Hudson.
