Does the BIOS have a setting where you can change the primary and 
secondary card around? I have one system where this is possible.
Also, some boards like the one I described disables the onboard when an 
AGP card is installed.

Still some BIOS versions allow you to initialize pci video over the 
integrated video.

Since you say that there is no jumper to configure, there should be some 
sort of BIOS option to disable, set it to secondary. Of course should 
and does are different animals.

Unless you try to perform a text install using xdriver=ati, I would not 
have a clue. Of course as Alan mentioned, you can find the pci ids and 
add them to the xorg.conf file with information you get from lspci 
regarding the video card IDs.
