Screen Resolution Selection in Etch

Just installed Etch (again) on another computer and an odd thing
happened.
The resolution was set to 640x480, and that is the only choice
(GNOME). I test a computer before install by running Knoppix, and it
detected the Voodoo 3 3dfx card and that the monitor could support
1600x1200 (Viewsonic 21" professional p225). So I was surprised that
the resolution was set so low, especially since this card is supported.

Unfortunately Debian can't seem to write to the floppy, USB device,
the FAT-16 second hard drive, or see the Windows network, so I made a
few notes about the Xorg.conf file.

Section "Module"
..."dri", "glx"

Section "Device"
Identifier "3Dfx Interactive, Inc. Voodoo 3"
Driver "tdfx"

Section "Monitor"
Identifier "P225"
Option "DPMS"

Section "Screen"
Identifier "Default Screen"
Device "3Dfx"
Monitor "P225"
Default Depth 16
SubSection "Display"
Depth 16
Modes {All common display resolutions)

Depth 24
Modes (All common display resolutions)

Would appreciate any help debugging the problem.

What does /var/log/Xorg.0.log say?
You cant have "(All common display resolutions)" in your /etc/X11/
xorg.conf-file, as the X11-server doesn't understand that.
(That is, give us ALL relevant sections, not only parts of it).
