Can you help again? Any other info that you may need? By default (after powerup) you'll see garbage on secondary monitors. They'll be up in 640x480/60Hz, but without usable picture. You must do 'con2fb /dev/fb1 /dev/tty5' to get usable picture on screen. And you must boot with 'video=scrollback:0', otherwise picture will get corrupted if you'll hit 'shift-pgup'. But until you hit shift-pgup, picture should be ok.
