My quest is at an end!
The G3 DT showed up yesterday and the lots of cards came in last week and I finally had a chance to get in to everything last night. As it turns out, the "original" OrangeLink card that was in the lot of many cards I bought was the second revision so I didn't bother testing it (though I will be doing so at some point this weekend). The G3 DT that omidimo found DID have the version 1 board which I put in my TAM and (after running the pci bridge patch), I'll let the pictures speak for themselves:
It doesn't show up as anything special in System Profiler, but a USB mouse and my Firewire hard drive showed up and worked without issue
The card in its new home
The version two card which I'll try out hopefully some time this weekend
The G3 DT was surprisingly well-equipped too, though the case is not in the greatest of shape. 640MB RAM, 4MB VRAM upgrade, the Wings card, and a PCI 10/100 ethernet card. Definitely going to swipe the VRAM upgrade for my G3 AiO as well as the RAM.
BIG thanks to omidimo for finding this machine!
