I don't know for sure, but I doubt it, unless it was flashed.

It is not going to work unflashed, and I don't think a flash exists. Sorry
:( The cards are cheap, though.

Thanks, mucho for the feedback, guys. Intuitively, I suspected this was likely the case, but didn't know for sure. It only occurred to me that this might be a possibility when someone on the Swap List listed a "Wanted to Buy" for a G5 Graphics Card, which is also a PCI-X card for Macs. OTOH Apparently I can use this card in one of the other PCI-X slots in the Mac Pro Tower. I don't know if this would allow for an expanded desktop or simply a mirror of the primary desktop.

All right, folks! I have been properly schooled on the difference between
PCI-X & a PCI-E. A fellow G-Lister has set me straight. I'm saying three
"Hail Steve Jobs" & a donating the card to a non-profit radio station.
Hopefully, this will reduce my time in spinning ball hell. Thanks, again!

I know you’ve already gotten your answer, but this seems noteably to me:
Intel Mac graphics cards have an EFI based firmware on them, so they are
compatible with the EFI based Intel macs. Otherwise the graphics card is
identical to a Power Mac or PC version.
Power Mac graphics cards have an Open Firmware based firmware on them.
And PC graphics cards have BIOS based firmware on them, or newer cards maybe
also have an EFI-aware firmware as well. But it’s propably different from the
one used in Intel Macs.
IF you can find an Open Firmware based firmware for that specific card, you
can try to flash it. If none is available there is now way. And flashing is
not so very trivial either.
One thing is interesting though: I’ve once used a PC version of a graphics
card in a Power Mac computer. Due to the BIOS based firmware, the computers’
Open Firmware was unable to initialize it and the screen stayed dark. I booted
into Linux (because that is what I used back then) and the Linux kernel
detected this PCIe graphics card and loaded the appropriate driver and with it
the card was initialized. So, once the operating system took over, it all
worked even though it was the wrong firmware on the graphics card.
On Mac OS X the graphics driver will not work though, because it has built-in
logic to check for certain Open Firmware variables (or EFI variables, if
you’re on Intel). In other words, it relies on Open Firmware (or EFI on Intel)
to initialize the card and takes over from there. Mac OS X will therefor never
work with an identical graphics card that has the wrong firmware on it.
Just to make things more complicated, I guess…
Cheers,
Andreas aka Mac User #330250
