ATI Radeon X1900 XT, Apple Upgrade Kit vs. BTO Option (Mac Pro 1,1) - Same?

Question

This question pertains to the ATI Radeon X1900 XT Video Card, which Apple offered as a BTO Option for the Mac Pro 1,1.
In September 2007 I purchased my Mac Pro 1,1 (2x Intel Xeon 3GHz Woodcrest) and configured it from Apple with the ATI Radeon X1900 as a BTO Option.
Now I know that a number of people initially experienced some problems with this card, but mine has worked perfectly all along. I run FCP, Aperature, and Adobe CS3, and the X1900 has performed excellent.
Leading to my question:
I own more than one Mac Pro 1,1. But the other two machines were not configured with the X1900. And for the past couple of years, I've been regularly searching to find (one or more) Genuine, Original Apple ATI X1900 XT Video Cards - either for sale by someone who has pulled out the X1900 from their Mac Pro 1,1; or, from an Official Apple Reseller. However, all that I've been able to find are - what appear to be either a "knock-off" third party version of the X1900 (flashed for Mac Pro), or; people and/or resellers who claim they are selling a Genuine, Original Apple ATI X1900 XT; except there's one major difference between all of those other video cards, and my X1900 (BTO from Apple, Mac Pro 1,1).
My X1900 does not have an S-Video Port. However, all of the other X1900 cards I've seen advertised for the Mac Pro are pictured with an S-Video Port - which again, mine does not have one.
I've spoken with both Apple Technical Support and Apple Care Representatives (Sr. Advisors), and I've asked them whether it's possible to identify a Genuine, Original Apple X1900; either by the serial number, or possibly by an Apple Part Number.
The Mac Pro 1,1 "Tech Specs" are listed on Apple's Support Site (support.apple.com/kb/SP30). Here, Apple does provide an Apple Part Number for the X1900 as an upgrade (MA631Z/A); however, nobody from Apple can tell from that part number - whether that Apple Part Number corresponds to an X1900 with an S-Video Port, or whether it's identical to the X1900 that was offered as a BTO Option for the Mac Pro 1,1; or whether that particular X1900 was part of an "Upgrade Kit" for the X1900 - which would've been available to purchase from Apple (Apple Store), sometime late in 2007 and/or early 2008. Further, I also know that Apple changed the actual Service Part Number a few times for the X1900.
What I'm trying to find out:
Has Apple ever directly sold, or, has Apple ever officially offered the X1900 w/ S-Video Port - under one of the following Apple Service Part Numbers (661-3297, 661-4335, 661-4911)??
Sorry for the super-long post.
It's just that this has been bugging me for like two years.
Thanks,
John

When I write, I often find that I end posts with what I wanted to say. Put summary at top helps.

I don't know. I do know some X1900s are being replaced even if out of warranty, as are 2600s also.
For $249 the ATI 5770.
