Description of Problem:

On a machine with 2 video cards (for example, one onboard and one in a PCI
slot), the installer is unable to determine which of them is "active" when
picking which video driver to use.One possible solution to this problem
would be to probe each and default to the one that has a monitor atatched.
(Or present a "you seem to have to video cards" screen.)

How Reproducible:

Attempt to install RedHat Linux 7.1 on a machine with two video cards.

Steps to Reproduce:
1. 
2. 
3. 

Actual Results:

Installer generally defaults to the first in bus order, generally the
onboard graphics card. Most likely, this is not the one that is intended.

Expected Results:

Pick the currently "live" graphics card. (the PCI one)
