Nice idea, but no joy. From a little code skimming I've done it seems 
that /dev/vcsN is the text content of the console, while /dev/vcsaN is 
its "text/attributes", whatever that means. I assume that /dev/ttyN is just 
the device to which a program sends things for display.

It looks as though a new format of codes is needed to switch blanking off: 
perhaps an escape string? That's a straw I'm clutching at, notice ;-)
