3 monitors, 2 nvidia cards - how to setup without xinerama?

Hi all,

I have 3 monitors and 2 nvidia cards attached to my computer at work. I can obtain 3 separate X screens and run 3 separate sessions of i3 using the DISPLAY=$DISPLAY i3 & trick, but I would like to have it so I am only running one session of i3 that sees all the monitors and still treats them independently. So far, I I have only been able to achieve this by turning on Xinerama and using the --force-xinerama option, but that isn't a solution because it kills 3d acceleration. I am also stuck using the prop. drivers because nouveau doesn't have support for OpenCL, which I also use. Following are my .xinitrc, xorg.conf, and xrandr output. Would someone be willing to take a look and help me figure out if you can do this? I thought you would be able to by RANDR 1.4. I have been using i3 on my laptop and think it is fantastic, I would really like to use it at work as well. Thanks!

.xinitrc

xscreensaver -nosplash &
udiskie &
CURRENT_DISPLAY=(`echo $DISPLAY | tr '.' ' '`)
( xcompmgr -CcFf &>/dev/null ) &
( xcompmgr -CcFf -d ${CURRENT_DISPLAY}.1 &>/dev/null ) &
( xcompmgr -CcFf -d ${CURRENT_DISPLAY}.2 &>/dev/null ) &
#exec i3 -V >> i3.log 2>&1
DISPLAY=:0.0 i3 &
DISPLAY=:0.1 i3 &
DISPLAY=:0.2 i3

xorg.conf
