I suffered a similar experience with a G450 PCI.  It is my understanding
that enabling high resolution modes on the DVI port requires some
extra fiddling in the driver, but Matrox provides no documentation
on this so XFree86/Xorg can't implement it.  Unless you can use the
proprietary drivers Matrox provides for some platforms, you're
effectively stuck with the analog VGA port.
