Since Xen lets you specify raw "cpuid" register values here, surely
this is flexible enough to allow us to support the mode=custom CPU
models ?
We would just need to make sure every bit poisition used either
0 or 1, and not 'x', so that we are fully overriding whatever
defaults are presented by the hypervisor "host" CPU model. Or is
life more complicated than that ?

Daniel
