Starting Chromium without checking for old session

[kosy]

I am preparing mini computer to be used as info screens in a hotel. It will not have a keyboard or mouse. I am starting x11vnc to be able to control it remotely and I am also starting Chromium in kiosk mode and that is working fine except when the computer is restarted (or the power is lost) when the browser always asks to restore last ression as it was not closed correctly. Can I use some switch along with --kiosk so it will not check for errors of old session when it is started?

I have found this site with all switches that can be used with chromium but do not know witch one I could use: http://peter.sh/experiments/chromium-command-line-switches/

best regards,
