No idea, I bought it used in germany. OF sees it as IMS,tt3d the chip is labeled 'Twin Turbo 128 3d', the ROM says 'Apple iX 3d 1.01'

ok, then it's an Ultimate Rez.

Yep, I can confirm this. The MacOS driver hangs occasionally if the card is behind the PCI bridge. ( and it hangs reproducable when you try to change resolution )

Well, this has an Apple ROM. Gives an OF text console. I'll try the generic kernel again, all newer kernels compiled from CVS were quite unusable...

Yep. The Millennium II drivers didn't work at all behind the bridge, a Millennium I did. 

have fun
