Similar problem here with two separate radeon cards: one 9200 AGP and 
one 9200 SE PCI.  Worked great on 6.8.2, but same xorg.conf on 6.9 or 
7.0 causes complete system lockup with screen on PCI card just a mass of 
various colors.  Log says since no monitor section for second port on 
each card, MergedFB/Clone mode disabled.  Going to go look for a bug on 
this and if none, will start one.
