How do they collide?
I have used on-board ATI with PCI Nvidia or the reverse on several different old computers. Sometimes it is tricky to get things to work, but IIRC, it was possible in each case.
The BIOS settings for which interface is primary may be tricky. You may need to experiment a little to see what those really do.
When doing such strange things with video interfaces, I never tried too hard to get any automatic creation of the final xorg.conf file to work. Maybe it could work, but even if so, finding out how to do that would be harder than making the final xorg.conf file manually.
As a first step, I usually used whatever automated process was appropriate to the situation (such as the Mepis liveCD and Mepis X windows assistant) to create an xorg.conf file for each of the video interfaces alone.
With a little knowledge of the rules of xorg.conf files, plus example content from the two individual xorg.conf files, it is pretty easy to create one xorg.conf file to handle both interfaces.
