Happy New Year all!
Leo, I believe there is a linux kernel parameter which will do what you 
require:
consoleblank=    [KNL] The console blank (screen saver) timeout in
            seconds. Defaults to 10*60 = 10mins. A value of 0
            disables the blank timer. [1]

there is always the option of using the serial console to catch any 
messages if your client & server machines have serial available!
