In fact, not having an Open Firmware compliant ROM on a PCI adapter breaks compliance to the PCI standard, which makes total sense.
stefan, doesn't that make every vga card out there a violator? does any good graphics hardware have fcode in the rom for init?
As far as I understand the specs, yes, this is true. Depending on what you consider good, maybe there are some cards - the Sun Ultra5/10 have PCI graphics adaptors that contain such a code, so it should be possible to use these when the basic API to OpenFirmware is working. I know that Adaptec has FCode Firmware on some of their scsi adaptors. I don't know how much these cards' hardware differs from their PC equivalents. Eventually it is even possible to reflash some of the PC cards with the Fcode firmware, but I don't know about legal issues when doing this. Though, at least Adaptec had FCode updates on their web page some time ago.
If at any point you get something going we would like to see about linking it in to linuxbios. If this works you will have more platforms to work with.
Since you have far more experience with the early setup code, I think this would be a very good symbiosis.
