6. should work for any PCI/AGP/PCIe card combination; both xinerama and
old style multi-head. Although I haven't tested with PCIe for lack of
having it, I've ran pretty much all other configurations with a scala of
cards: Matrox G400 (agp), Matrox Millenium II PCI, Radeon 7500 PCI/AGP,
Radeon 9200 AGP, NVidiot something AGP, i815 AGP.

As for your wish to drive 2 DVI ports, same here. I was hoping:
would work. But alas, no external TDMS support :-(

If intel would add a second DVI output to their i965 graphics chip (and
mobo makers would actually build a board with it) I might even buy intel
