Both apm_saver and green_saver are essentially (once you get past all the
screensaver setup code) one-line routines to turn off the display. I think
it would make sense to both tell the VGA chip to blank (green_saver) and
tell APM to shut down (apm_saver) with proper #ifdeffing around the APM
stuff.
I also think it would make sense to do this inside dev/fb/splash.c (or
perhaps dev/syscons/syscons.c) instead of inside each screensaver, so that
it's automatically handled. And maybe a new 'vidcontrol' option to set the
blanking delay (as opposed to the screensaver delay) would be necessary.
There may be an even better place to put this, but I am mostly unfamiliar
with the kernel source tree and as such I won't attempt to write a patch
for this yet.
