I worked on a project developing a PCI-X card a couple of years ago and we ran these cards in 64-bit, 3.3v, 66MHz PCI slots for most all of our testing (except when performance was being measured). Consequently, I would argue that Stephen is correct in that a PCI card should fit into a PCI-X slot so long as the PCI card is 3.3v compatible (keyway is in the right place).
