there's the problem.  no agp support.  I think 6.7 was too old to
support PCI radeons by default.  You may need to upgrade to 6.8.x.  I
think there was an option to force PCI-GART, but I can't remember off
hand.
you might try:
	Option     "ForcePCIMode"    "true"
or:
	Option     "BusType"      "PCI"
