When it comes to card initialisation, perhaps you could take a look at linuxbios. They are working to get vga support up and running (some have been successful). Otherwise you may want to take a look at qemu (unfortunately they don't support mips but they do support ppc), or bochs. I think X also have the ability to "init" cards, but I'm not sure on that...
