why isnt AGPFastWrite Woring on my nvidia system (all seems to be set-up correctly)


Im trying to enable fastWrites for my Nvidia GeFOrce FX 5700 LE card, on my Nforce3-250 motherboard...

some vital stats....

nvidia cdriver config file....
Code:
chris@localhost ~ $ cat /etc/modules.d/nvidia
# Nvidia drivers support
alias char-major-195 nvidia
alias /dev/nvidiactl char-major-195

#   To enable Side Band Adressing:  NVreg_EnableAGPSBA=1

#   To enable Fast Writes: NVreg_EnableAGPFW=1

# To enable both for instance, uncomment following line:
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1
what the /proc/ filesystem has to say about FastWrites
Code:
chris@localhost ~ $ cat /proc/driver/nvidia/agp/host-bridge
Host Bridge:     PCI device 10de:00e1
Fast Writes:     Supported
SBA:             Supported
AGP Rates:       8x 4x
Registers:       0x1f00421b:0x00000312
chris@localhost ~ $ cat /proc/driver/nvidia/agp/card
Fast Writes:     Supported
SBA:             Supported
AGP Rates:       8x 4x
Registers:       0x1f000e1b:0x1f004312
chris@localhost ~ $ cat /proc/driver/nvidia/agp/status
Status:          Enabled
Driver:          AGPGART
AGP Rate:        8x
Fast Writes:     Enabled
SBA:             Enabled
And this is part of my Xorg.conf
Code:
Section "Device"
    Identifier  "myNvidia"
    #Driver      "nv"
    Driver      "nvidia"
    VideoRam    131072

    #added for transparency
    Option      "RenderAccel" "true"
    Option "AllowGLXWithComposite" "true"

    Option      "EnablePageFlip"        "yes"   #[<bool>] Improves performance
    Option      "AGPFastWrite"          "yes"   #[<bool>]

    # Insert Clocks lines here if appropriate
EndSection

Seems everything SHOULD work... but this keeps poping up in my Xorg LOG.
Code:
(WW) NVIDIA(0): Option "AGPFastWrite" is not used
What am i missing ?
are there any other options that may conflict woth FastWrites that i have to remove ???

whats the deal ?

In Slackware i put this in /etc/modprobe.conf:
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1
alias char-major-195* nvidia

and i reboot.

But as Nvidia tell us:
SBA and Fast Writes indicate whether either one of the features is
currently in use. Please note that several factors decide if support
for either will be enabled. First of all, both the AGP card and the
host bridge must support the feature. Even if both do support it, the
driver may decide not to use it in favor of system stability. This is
particularly true of AGP Fast Writes.
