I was able to reduce video artifacts to a minimum (seemingly
acceptable ;-) by setting 

- millennium to 800x600-60
- G400 1st head to 800x600-90
- G400 2nd head to 800x600-75

These are standard framebuffer modes found in /etc/fb.modes. I am
getting most artifacts when setting both heads of the G400 to the same
fb mode - which one does not influence things too much.

Thanks for your help

Carlo
