Because of the above limitation I've thrown the G400 into a corner where I hope it will feel appropriately unloved, and went back to a Matrox Millenium II PCI and MM II AGP for my two screens (1600x1200 each). I mention this because I don't remember the details, but the syntax of XF86Config for configuring dual-head operation with the standard XF86 mga driver is different from the Matrox mga driver. Using the Matrox mga driver (as you must with the G400), there is a `Screen' attribute for the "device" section. I know this is vague, but I can't remember exactly. Just keep fiddling, I was able to get it working.
