All that was asked was how to plug another video card into the
computer. No mention of actually having it do anything, or even
work....

Yes, exactly. The original poster didn't mention what the
purpose of doing this was. Perhaps it was to troubleshoot a
burned out video card or motherboard for midterms... It pays to
form questions with more information....

Well there is now. Check out the latest kernel (2.1.115 or
2.1.116).
