Xinerama works just fine, and I'm using it on machines here to run four
monitors across two cards just merrily.

Use the binary nvidia driver and the inbuilt TwinView, as it's better than
using Xinerama.  I believe xorg-x11-drv-nvidia from rpmfusion is probably your
easiest option with Fedora.

Setup your X config.  I tend to just do it by hand.  Take a normal X config
that works with one screen.  Go to the Device section:

Section "Device"
         Identifier  "Videocard0"
         Driver      "nvidia"
         VendorName  "nVidia"
         BoardName   "Quadro FX 4500"
         Option      "TwinView" "on"
         Option      "MetaModes" "1280x1024, 1280x1024"
         Option      "TwinViewOrientation" "LeftOf"
         Option      "AddARGBGLXVisuals" "True"
EndSection

Do not attempt to enable Xinerama elsewhere in your X config.
