Enabling fast writes is an "nvidia" module option, which you can pass on
an "options" line in your /etc/modprobe.conf file; i.e.,
in /etc/modprobe.conf,

alias char-major-195* nvidia
options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1


Also ... You may wish to tweak the Nvidia settings in your xorg.conf
file ...

Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"
        VendorName  "Videocard vendor"
        BoardName   "VESA driver (generic)"
        Option          "RenderAccel" "1"
        Option          "CursorShadow" "1"
        #Option          "AllowGLXWithComposite"
        Option          "NvAGP" "1"
        Option          "NoLogo" "1"
EndSection


(If I'm not mistaken, using the "AllowGLXWithComposite" option with the
"RenderAccel" option is supposedly quite experimental.  Your mileage may
vary.)

cheers,
