This is probably from (in beep.c):

  if (ioctl(console_fd, EVIOCGSND(0)) != -1)
    console_type = BEEP_TYPE_EVDEV;
  else
    console_type = BEEP_TYPE_CONSOLE;

where the missing ioctl is completely expected and not worth a
warning.  So yes, this looks like a (cosmetic) bug.

Thanks.  That patch is not queued for 3.2.y --- should it be?
