Sorry...
cmhaas,
sorry ... but there is no ROM for older mac pros.
Early 2008 model details:
The reason for this incompatibility to my knowledge is because Early 2008 model uses 64 bit EFI ROM and prior have 32 bit EFI ROM.
I think that there is a FX 4500 board which runs on early Intel Mac Pro.
But I do not have one of these so cannot get a ROM extract.
There is reasonable demand for Mac'ed FX 5600 on ebay, so if you purchased board especially for Mac, then you should be able to at least recoup your purchase price.
Anyhow here is "About this Mac" image for flashed FX 5600 working...
Cheers,
Zebity.
