It's not PCI-X itself, but it's compatible with PCI-X slots: it will
work in a 3.3V or 5V slot.

Well, I think in general companies downplay their PCI support because
only us whackos with dual-head systems care. If I could get a
reasonable AGP dual-head card with DVI-D output and good, reliable
2D/3D performance under Linux, I'd probably go that route; alas, I
haven't found any. Do you know of any?

Mine seems to have trouble with memory region remapping: the BIOS
configures the PCI card with two overlapping memory regions (!!),
which Linux then remaps to fd000000 and c0000000. This is fine,
seeing as the nv driver manages to cope with it; but I suspect the
nvidia driver can't, for some unknown reason.

Hey, I even offered to give them root on my box. We'll see if they
have anything to say. :)
