I can't speak for the others but according to my Wyse 50 manual the S.SAVER feature in the field level 4 menu has a default value of OFF.
My recollection is that this was common among the VDTs which suffered considerably from burn-in. Many of the later models had the feature but it was a hardware setting controlled via a configuration menu or a dip-switch. You want the setting to persist across logins and power cycling.
It really should be disabled in-kernel by default. The distribution RC scripts would as a default then enable it late in the boot process. In a server setting where it isn't wanted the admin should know enough to prevent its being enabled.
I too have been bitten by this on servers where the console display is either powered down or disconnected for months at a time. The error messages leading to the hang may be in the display buffer but they can't be seen.
