xorg.0.log showing intel driver ignoring option to disable external output

In my xorg.conf, I have the following section:

Section "Monitor"
        Identifier "VGA"
        Option "Enable"  "false"
EndSection

This is picked up by X, as reflected by the following excerpt from Xorg.0.log:

(II) intel(0): Output VGA using monitor section VGA
(**) intel(0): Option "Enable" "false"

However, the display is enabled nonetheless:

(II) intel(0): Output VGA connected

<snip>

(II) intel(0): Output VGA using initial mode 1024x768

The full log is attached.

Other info requested:

% uname -m
i686

% pkg-config --modversion libdrm
2.3.1

Mesa version 7.2

XServer 1.5.3

intel driver version 2.4.3

Any more info needed, just let me know :-)

From xorg.conf man:

Option "Enable"  "bool"
  This optional entry specifies whether the monitor should be turned on at startup. By default,  the server will attempt to enable all connected monitors.  (RandR 1.2-supporting drivers only)

"Enable" is only used for output enabling, _not_ for output disabling (try "Disable" or "Ignore" instead). 

Also see code of xf86OutputEnabled().
