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).
