Success!
Hi everyone!
I successfully flashed my new Sapphire Radeon HD 4890 1GB. I followed the instructions from mfka on page 3 of this thread and it worked like a charm.
If there are any other people from germany who would also like to get this card and flash it, here is what I got:
Bought the card here:
http://www.mindfactory.de/product_info.php/info/p619402_1024MB-Sapphire-Radeon-HD4890-GDDR5-PCIe.html
I got the cable (only needed one, I already had one from my X1900XT) from a friend who works at the Apple reseller mStore. He said that any mStore would order the cable for you if you ask. It was actually specified as a cable for the nVidia Quadro FX 4500, but it turned out to be exactly same as the one I had from my X1900XT.

Useful specs:
- mac pro 1,1 with OSX 10.6.1
-
Model: HD4890 1G GDDR5 PCI-E HDMI/DVI-I/DP
-
PN: 288-1E115-D20SA
-
SKU: 11150-11-20R
-
RoHS: A093800028080
Additional feedback: Before ordering I tried to find out wether the card I wanted to order would have Hynix or Qimonda ram on it. I contacted Sapphire support and sent them the PN and SKU numbers from the retailers website. They replied that they needed the RoHS number to determine this. The RoHS number is printed on the box, so a retailer who has the card in stock should be able to give you the number and you can ask Sapphire support before ordering.
Btw, you don't have to remove the cooling unit to determine the ram manufacturer! I could clearly see the Qimonda-logo on the ram chip on the bottom right of the picture mfka posted.
Many thanks to everyone who contributed to this noble cause
, especially Cindori (donation on the way) for his flash-app and Peloche for the working rom!
