enable pci quartz extreme

there is some misinformation on the interweb stating that quartz extreme can either be enabled for agp devices or pci devices, but not both simultaneously. as greg would say, this is a crock. adjust your CoreGraphics Configuration.plist accordingly:

/System/Library/Frameworks/ApplicationServices.framework/Versions/A/
Frameworks/CoreGraphics.framework/Versions/A/Resources/Configuration.plist


<key>GLCompositorRequiredClasses</key>
    <array>
        <string>IOAGPDevice</string>
        <string>IOPCIDevice</string>
    </array>
