Thanks for you reply.
How do I check that my vendor string reads ATI?

Section "Device"
Identifier "i915"
Driver "i810"
VendorName "i915"
BoardName "i915"
Option "NoAccel" "false"
Option "DRI" "true"
EndSection

Section "Device"
Identifier "ATI"
Driver "fglrx"
Option "mtrr" "off"
Option "OpenGLOverlay" "off"
Option "no_accel" "no"
Option "no_dri" "no"
EndSection
