My laptop has X600 that uses PCI-Express.
I cannot find anyway of increasing memory.
My xorg.conf radeon settings are:

Section "Device"
        Identifier      "ATI Graphics Adapter connector 0"
        Driver          "radeon"

        Option          "DynamicClocks" "on"

    # This allows X to use MergedFB if the external monitor is not connected
    # when I start X.  The ranges are taken from DDC values of the CTX monitor
    # I use at the office; as listed in Xorg.log.

    # scrolling for the 1024x768 part.
        Option          "MergedNonRectangular"  "true"
