Ok! This may be another silly idea. But would it be possible to load a cpuid patcher/simulator from a bootloader just before loading mach_kernel? I don't know if this would be possible as I'm not a programmer, but I was thinking QEMU, which can even simulate lots of non-intel cpu architectures using intel/amd cpus. I know tha QEMU is an open-sourced program that needs to be loaded UNDER an os in order to be used but.....
If there could be something like that, all amd users could run unmodified vanilla kernels. So I would like to have an answer from people who have the appropriate knowledge on programming.
