X.org with multiple video cards

[greml!n]

I have a nforce2 motherboard (w/ built in video chip) in addition to a nvidia GeForce4 Ti 4200. I currently have the nforce video disabled and only use the 4200, which works perfectly in x-org 6.8.

So here it comes.

1. Can I configure x.org (and the kernel, and udev, etc) to recognize both video cards?

2. Can I configure x.org to use the nforce2 as a secondary screen, as though it were a dual head configuration?

3. Can I have this controllable, so that it only happens occassionally? In other words, the monitor I connect to the nforce2 may not always be connected.

Thanks in advance!
