I'm quite sure, that the matrox supports "real" xinerama.
I have 2 devices and 2 screen in xorg.conf and the
ServerLayout is like:
Section "ServerLayout"
Identifier "Layout[all]"
InputDevice "Keyboard[0]" "CoreKeyboard"
InputDevice "Mouse[1]" "CorePointer"
Option "Clone" "off"
Option "Xinerama" "on"
Screen "Screen[1]" LeftOf "Screen[0]"
Screen "Screen[0]"
EndSection
The mga driver can run in "Merged" mode, too, which is the same like
Twinview for nv cards where you have only one device which fires both
screens. But I don't use that since the window manager won't support it
and it doesn't work with my configuration anyway.
If ran dispwin with debug output:

The first one works and loads the calibration to display 1. The seconds
doesn't do anything. Specifing other display numbers ore things like
-d1,2 -d2,1 -d 2,2 etc. doesn't work either.
Additional output see below.
Would it make sense to discuss that on the xorg mailing list?

Volker

Btw: RANDR is not support since DRI doesn't work when the card is in
xinerama mode. This is one of the limitations of the G550.
