Yup, it seem that if you have multiple video cards and/or multiple 
monitors X gets very confused. I'm having problems myself, and it's 
looking like X is the culprit.

I don't believe that X ignores xorg.conf. If you make changes to 
xorg.conf, restart X, then examine the logs, you should see you're 
additions being actioned.

There does seem to be quite a bit of confusion, though, about what's 
going on.
