I have never been able to get SAX to set up dual monitor in SUSE 10.0
(SUSE9.x was no problem though, and done as described).

I just manually edited the xorg.conf file. Simple.. easy to do, and
well documented. I don't recommend Xinerama at all if you have a
nVidia card. Instead use the _much_ better Twinview option in the
nVidia driver.

I have this set up on my nVidia 6600 and it works perfectly (primary
monitor on the right and secondary monitor on the left). I have full
OpenGL (3D accelleration) and glxgears actually gives me slightly more
fps than in single monitor mode... forget the actual value at the
moment. All my games installed in Cedega work properly (full screen
or windowed). All my applications behave properly (ie full screen on
one monitor only etc.).

Here's the relevant parts of my xorg.conf with comments:
# I just included the Module section so you could see what I'm
loading... the default
# generated by your original SAX config should be the same
Section "Module"
Load "dbe"
Load "type1"
Load "freetype"
Load "extmod"
Load "glx"
Load "v4l"

# I had to set the display size to double width and single height to
get Acrobat Reader
# to behave properly. If you don't do this, there is a good chance that PDFs
# will be unreadable. The rest of the settings are for my primary
monitor, and left
# over from my original SAX config for single monitor. They are used
for your primary
# monitor.
