You mean stuff like;

Section "ServerLayout"
	Option	       "AIGLX" "true"
        .
        . Other things go here
        .
EndSection

# ATI only I believe
Section "ServerFlags"
	Option	    "AIGLX"     "on"
	Option      "IgnoreABI" "on"
EndSection

Section "Device"
        .
        .
        .
        Option      "XAANoOffscreenPixmaps" "true"
        Option      "RenderAccel" "on"
        Option      "AccelMethod"   "EXA"
        .
        .
        .
EndSection

I'm not sure about the XAANoOffscreenPixmaps, I've got it in there even
though I use EXA. So that line is probably bogus.
