To expand on Jeff's ever so helpful response...

<rant>
I don't use xinerama anymore, since the good ximian folks seem utterly
uninterested in understanding why evo is the only application on the
planet (at least, the only one I've ever seen) that won't play nice with
xinerama (http://bugzilla.ximian.com/show_bug.cgi?id=20473).  And
although xinerama is very cool software, and has some distinct
advantages, and I really like it and wish I could use it, evo is even
cooler software, and I want evo even more than I want xinerama.

I feel much better now...  Anyway, it is possible to get a single
logical screen on the G450 without xinerama.  The mga xfree86 driver has
a "MergedFB" option that you can set which makes the two heads look like
one big framebuffer to xfree86.  It's not as nice as xinerama, since
nobody but the driver knows that you have two separate screens (so for
example, your window manager can't be smart about window placement or
zooming, etc...), but it gets the job done.  The easiest way to set up
the G450 this way is to simply use Matrox's "PowerDesk" GUI tool to do
it.  If you want to manually edit the XF86Config-4 file, you'll need to
create a single screen, and them make sure the "Monitor2Position",
"MergedFB", "MetaModes", "Monitor2HSync", and "Monitor2VRefresh" options
are set appropriately for the screen, then you'll also want a "Display"
subsection.  Here's my "Screen" section as an example (I'm running my
two heads at different resolutions, don't let that mess you up).

    Section "Screen"
        Identifier "Display Merged"
        Device     "G450"
        Monitor    "Display Merged"
        DefaultDepth     16
        Option      "Monitor2Position" "RightOf"
        Option      "MergedFB"
        Option      "MetaModes" "1600x1024-1280x1024 "
        Option      "Monitor2HSync" "30.0-96.0 "
        Option      "Monitor2VRefresh" "50.0-160.0 "
        SubSection "Display"
                Virtual   2880 1024
                Depth     16
                Modes    "1600x1024" "1280x1024"
        EndSubSection
    EndSection
    

Cheers!
