My experience with the nvidia driver's equivalent function to xinerama 
is that what you really need is one doublewide image, possibly made of 
two smaller images.

You can write a bash script to do this, using convert/mogrify.

xinsetbg.sh:
#!/bin/bash
cp $1 /tmp/input1.png
cp $2 /tmp/input2.png
mogrify -rotate 90 /tmp/input1.png
mogrify -rotate 90 /tmp/input2.png
convert -append /tmp/input1.png /tmp/input2.png /tmp/output.png
mogrify -rotate -90 /tmp/output.png
display -window root /tmp/output.png
rm /tmp/input1.jpg /tmp/input2.png /tmp/output.png

xinsetbg.sh myimageleft.png myimageright.png

All of the annoying rotation is necessary because convert -append joins 
the images vertically, and I don't know of an alternative switch for 
doing it horizontally.

Hope that helps.
