Need driver for graphics card: Nvidia Vanta & need to set dpi

Using Debian Lenny 5.0.2
Nvidia vanta graphics card: need driver, need to set dpi

This is my graphics card:
01:00.0 VGA compatible controller: nVidia Corporation NV6 [Vanta/Vanta LT] (rev 15)

I am using the nv driver at the moment.

I am having trouble setting the dpi on my monitor.
I am trying to set the dpi to 96 x 96
I used the following formula to configure the display size
25.4/96 x resolution

This is part of my xorg.conf:

when I set the resolution to 1280 x 1024 I get

Code:

---

xdpyinfo | grep resolution
resolution:    90x96 dots per inch

---

with 1152x864 I get 81x81 dots per inch

with 1024x768 I get 72x72 dots per inch

What am I doing wrong in setting the dpi?
Is nv the best driver for my card, is there other drivers I could try that
would work better?
I don't really need a 3D driver so I didn't want to install the Nvidia
driver if it wasn't necessary.

Thanks.

You might want to see if there is a native nVidia driver for this board on the nVidia web site. They usually work better for supporting high-resolution graphics than the default nv or vesa drivers.
