I've got it working on my G400 dual head. The binary driver can
be downloaded from Matrox's web site. It's a new mga_drv.o to replace
the one supplied by xserver-xfree86. It works fine on Debian.
One annoying thing though is that the pixel clock on the second
head is limited to 110MHz by the driver. My second monitor is
a fixed frequency monitor requiring 1280x1024, which needs a dot
clock of > 110 MHz. Fortunately that 110 constant is in the
open-source part of Matrox's driver, so I just changed it and
recompiled.
I've also noticed that some of the xscreensaver screen savers
crash the X server; when using the XFree86 original mga_drv.o,
they just generate error messages instead.
