With that hint, I've been experimenting with various flatscreens I ahve
access to.  So far, each of the ones I've experimented with won't
(soft) power on with buttons held down, except for one magic button
combination.  All but one of them then have new options in the OSD when
powered on with that magic combination.  Unfortunately none of them are
as interesting/useful as yours....

Quite.  That sort of thing is on the order of the Konami code.

Actually, that's another thing that bothers me about flatscreens (all
of them, in my limited experience): none of them are willing to display
their OSD unless they are being fed a displayable video signal.  (For
CRTs this kind of makes sense; you need scan frequencies to have a
display raster to superimpose the OSD on.  For flatscreens it doesn't;
there is no technical reason it couldn't be made to display whatever it
pleases wherever it pleases whenever the backlight is on.)
