I didn't, at first, since I thought that I knew what You where talking 
about.

My /etc/X11/xorg.conf is now like this;

Section "Monitor"
         Identifier      "Default Monitor"
EndSection

Section "Screen"
         Identifier      "Default Screen"
         Device          "Default Device"
         Monitor         "Default Monitor"
#       DefaultDepth 16 # option that speeds older hardware
EndSection

Section "Device"
         Driver  "radeon"
         Identifier "Default Device"
         BusID "PCI:0:1:0:0"
         #ChipID 0x68d9
         Option "SwapbuffersWait" "off"
         Option "ColorTiling"  "on"
         Option "ColorTiling2D" "on"
EndSection

After a 'X :1' /var/log/Xorg.1.log says that it's using that conf;

[ 83895.530] (==) Using config file: "/etc/X11/xorg.conf"
[ 83895.530] (==) Using system config directory "/usr/share/X11/xorg.conf.d"

But the SwapbuffersWait is still enabled?

[ 84199.032] (==) RADEON(0): Depth 24, (--) framebuffer bpp 32
[ 84199.032] (II) RADEON(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp pixmaps)

[ 84199.033] (II) RADEON(0): KMS Color Tiling: enabled
[ 84199.033] (II) RADEON(0): KMS Pageflipping: enabled
[ 84199.033] (II) RADEON(0): SwapBuffers wait for vsync: enabled

I'll have to dig further around in /usr/share/X11/xorg.conf.d if there's 
something over-riding stuff.

Sometimes I long for the slackware way of doing things, i.e. nothing. The 
user does everything from scratch.
