Hi,
  is it complete diff between Linus/Alan tree and current linuxconsole
CVS or is it an addition to linuxconsole CVS (I did not look at patch
yet and because of I have no linuxconsole CVS copy here yet, I'm asking...)

I think that for backward compatibility you should add new ioctl
OPENVT2, which opens VT on specific output device. Old code (simple
open /dev/tty* and OPENVT ioctl) should use same lowlevel device as
current->tty uses... I think... Probably with exception that if
current->tty is not VT, you should use first head (for use by init, for
example, which is connected to /dev/console).

Create per-VT blanking timers which will expire individually and which
are restarted on keypress (on that VT) and console switch... Looks like
easiest solution to me. Another solution is glue it together as 'seat'
(all kbds, mouses and monitors at one place), but this does not
work correctly if you take into account that app can disable blanking
for such VT (XFree and fbtv does it, for example). Only unfortunate thing 
is that currently setting VT blanking period is per-system and not per-VT. 
But we can emulate it...
