Probably not. That's why I said: Don't patch the kernel but patch the
tools creating the code using CPUID by making the tools create fake code.
Eg make the assembler replace usagce of CPUID by some other assembler
code returning a constant string. So after having done this no
executable should contain tha CPUID instruction anymore. However this
can break code
