In case something goes wrong and you end up misflashing your stock Mac Pro card, here is a list of the ROM's with downloads that i'm putting together for people to use. I'm going to complete it over time as I bring the ROM's together.
These are stock Intel roms ONLY, not custom ones. Any help for getting the stock roms that I don't have here yet is greatly appreciated! Also, do let me know if anything seems to be wrong with any of these roms, like if I get the wrong one.
Some of these I have personally dumped from Mac cards, some I have found around the internet.
As far as I personally care, you can do whatever you want with these ROM's. They're Nvidia's, not mine.

http://dl.dropbox.com/u/4133784/OrigRom/evga285m.romCan flash: GTX 285's, GTX 260, GTX 280 Unconfirmed (Soldering required. Only works on the 1GB/896MB versions. From what i've seen, GTX 260's with the plate underneath and GTX 280's will have an issue with the fan spinning wildly)
-HD 4870 512MB
http://dl.dropbox.com/u/4133784/OrigRom/Mac4870.ROMCan Flash: some Reference HD 4870 512MB's.

-Quadro 4800 Mac EFI64
http://dl.dropbox.com/u/4133784/OrigRom/FX4800M.ROM (Thanks to Rominator!)
Can flash: PC Quadro FX 4800? (Soldering required and isn't recommended. Has an issue with the Fan spinning, according to Synthetix)
-Quadro 4000 Mac EFI64
http://dl.dropbox.com/u/4133784/OrigRom/Q4000MAC.romCan flash: PC Quadro 4000? (Soldering required and not recommended. Someone please confirm this can flash IF you have the soldering confidence, I assume that it can flash since the PCB looks the same)
-Quadro 4500 Mac EFI32
http://dl.dropbox.com/u/4133784/OrigRom/FX4500EFI32.romCan flash: PC Quadro 4500 (Soldering required, unconfirmed.)
-Quadro FX 5600 EFI64
http://dl.dropbox.com/u/4133784/OrigRom/MCQ5600.ROMCan flash: PC Quadro 5600 (No soldering required?)
-HD 3870 512MB
http://dl.dropbox.com/u/4133784/OrigRom/3870Mac.ROMCan flash: None? (Soldering technically required. The issue seems to be with a what a friend of mine says is an Inductor, which on the mac version, is labelled "R47", but on the PC Version is labelled "R10". That's the only physical difference I could see between the PC and Mac versions, besides the EEPROM. Can't find any info on this.)
-Apple HD 5770
(ROM Needed, searching...)
Can flash: NONE. Use one of the custom roms instead for PC 5770s. Please go to one of the applicable threads for info on flashing these.
-Apple HD 5870
(ROM Needed, searching...)
Can flash: NONE. Use one of the custom roms instead for PC 5870s. Please go to one of the applicable threads for flashing these.
Let me know if I missed any cards.
I'm not responsible if you try soldering or flashing, and something goes wrong. I am doing my best to ensure accuracy, but in case the wrong ROM slips through, please let me know, and I will correct it.
I might post up some Video tutorials for flashing some of these soon, if anyone wants me to.
