Whether it's an Open Firmware card or not can be read from the PCI headers stored in the ROM. Check the romheaders utility from OpenBIOS CVS ( http://www.openbios.org/ ) Look at the code here: http://cvs.openbios.org/cgi-dom/viewcvs.cgi/utils/romheaders.c?rev=1.2&content-type=text/vnd.viewcvs-markup The program prints whether the rom is OpenFirmware, x86 or HP PA-Risc. Note that graphics cards can theoretically contain ROM images for both x86 and OF in one chip.
Yup, "Mac" cards can contain in theory both OF and x86 BIOS drivers, though I yet have to find a vendor doing that.... Thanks for the pointers to code, I'll dig that out.
